AN2635, On-Chip FLASH Programming Routines

RAM In general, RAM in Table 1 indicates the RAM start address.

See Table 2 for RAM start locations for specific MCUs.

For example, the RAM start address for the MC68HC908LB8 (and each MCU currently in the table) is $80.

CTRLBYT The control byte (CTRLBYT) is located at RAM address RAM+$8 and is us
