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 used for the ERARNGE routine. In the case of the MC68HC908LB8,.
