2.5 Monitor ROM
2.6 Program EEPROM/ROM
2.7 EEPROM
Technical Data
The user RAM consists of 192 bytes ranging from $0040 to $00FF. The
stack begins at address $00FF. The stack pointer can access 64 bytes
of RAM in the range $00FF to $00C0.
The stack is located in the RAM address space. Data written to
addresses within the stack address range could be overwritten during
stack activity.
The monitor ROM ranges from $3F00 to $3FEF. The vectors for the
bootloader are located from $3FE0 to $3FEF.
The program EEPROM holds 7952 bytes in total. The mask option
register is located at address $2000. The 7935 bytes of the program
EEPROM are located from $2001 to $3EFF, plus 16 bytes of user
vectors from $3FF0 to $3FFF. The user programs the EEPROM on a 4
byte erase basis by manipulating the programming register located at
address $000D. Refer to
This EEPROM is replaced by an 8K ROM in the MC68HC05PV8,
ranging from $2000 to $3EFF and $3FF0 to $3FFF. Mask options are
controlled by the contents of location $2000. Refer to
Program EEPROM
The 128 bytes of EEPROM are located from $0180 to $01FF. The user
programs the EEPROM on a single-byte basis by manipulating the
programming register, located at address $000C. Refer to
