2.4 RAM
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.
2.5 Monitor ROM
The monitor ROM ranges from $3F00 to $3FEF. The vectors for the
bootloader are located from $3FE0 to $3FEF.
2.6 Program EEPROM/ROM
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 Section 14. Program EEPROM for details.
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 Section 14.
Program EEPROM for coding details.
2.7 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 Section 13.
EEPROM for programming details.
