Full details are contained in the text, however, the key features are: . Explicit declaration of macro names, baud rate and com port . Simplification of boot type talker selection . Simplification of directory structure by creation of new .XOO files . Feature to allow parameters to be passed to the AUTOSTART macro . New single file for help Placing of .MAP files --------------------- The PCbug11 documentation indicates that any .MAP files should be placed in the user's working directory. In V3.20 PCbug11 will not find the user's .MAP file unless it is in the same directory as PCBUG11 itself. PCbug11 V3.21 Information S-Records of more than 8KB -------------------------- A problem existed in earlier versions when loading or verifying S-records of more than 8Kbytes. This occurred when an S-record exceeded the PC internal 8Kbyte boundary. This could cause the PC to crash or cause strange graphic effects. This has now been remedied. Programming 711 parts --------------------- 68HC711 parts may be programmed more quickly using PCbug11 if an alternative crystal is used. If a crystal of 4.9152MHz is used then the HC11 is capable of communicating at 38400 Baud. This in turn reduces the programming time required by internal EPROM to one quarter of the normal time. The method requires a talker which initialises the SCI properly, the option baud=4800 to start PCbug11, and the digit 7 as a prefix to the bootloader type. A talker called TALK7E.BOO is supplied to program the 711E9 part. To use this talker the command line should be: PCBUG11 -7E baud=4800 On detecting the presence of the 7 and the baud=4800 options together, PCbug11 will use a default baud rate of 38400. If either of these options are missing then PCbug11 will default to its standard baud rate. PCbug11 V3.22 Information EEPROM and EPROM bugs --------------------- A possibility existed that the EPROM and EEPROM functions would not work with certain options. This concerns mainly options - A/D/K. Option D would allow all the normally disallowed commands and would not program properly. K would not program EEPROM or EPROM properly and A would not program EEPROM correctly. This bug has been fixed on the current version. PCbug11 V3.23 Information This document notes the changes made to PCbug11 for revision 3.23. The changes are noted with respect to V3.22. See also PCbug11 V3.22 Information. CONTROL command options ----------------------- Two options have been added to allow the location of the PPROG (EEPROM) and EPROG (EPROM) programming registers to be moved by the user. This may be necessary in the future as the HC11 family develops. The address of these registers may be the same - i.e. one register performing both tasks. The current values are displayed using the CONTROL command on its own. The values may be changed using the format CONTROL PPROG addr (addr is the address to be used) CONTROL EPROG addr (addr is the address to be used) Note that PCbug11 assumes that the relevant bits in each register maintains the same position as in the 711E9. User Map files -------------- This must now be placed in the user's working directory as described in the manual Command Line Compiler --------------------- The crystal value used parameter entered to the command line compiler is now given in KHz. This will allow the use of an extended range of values. EPROM Command ------------- An EPROM memory range error now reads 'Invalid EPROM address range'. EPROM/EEPROM Programming Error ------------------------------ The error displayed is now 'Programming t/out' or 'Programming cmd' depending on the failure. Loading and Verifying S-records ------------------------------- An upgrade here allows users to load and verify S-record files which contain backward discontinuous S-records. The code was already able to handle forward jumps in the S-record but not backward jumps. This is now allowed. Automatic Recognition --------------------- PCbug11 now has the capability of recognising which HC11 is in use from the contents of the boot ROM. The boot ROM contains information in two bytes which help to describe the part in use. PCbug11 reads these and displays the version in use by the MCU : label. Note that some MCUs may not be recognised correctly by this feature ‹‚.ŒÆACbug11 V3.20 Information Command Line Ateration ---------------------- PCbug11's DOS command line has been significantly cha€›³•¬¶¸Ôÿ[ t v ,Ìå ¯ Û î ŒœÈ×/OÑò÷zþýýþýýþýþýýýýýýýýýõ!$€›³Ë6~½í4w“•¬Ã›¸Ôðýÿ-SUgiƒY [ v ¤ Þ ,ÄÆÈÊÌåþ› Ù Û ŠŒœ¬1ÆÈ×æ-/OoÏÑòõ÷%'èwzûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûûND ÞúzJ øúÿÿÿÿÿÿ€ €z(Times New Roman Symbol&ArialEpson Stylus 800+LPT1:epepstEpson Stylus 800+ Dj' š4hh¡rú €€Û"ˆÄ©„2³Aµóe 5LE-MIEUX VincentLE-MIEUX Vincent
