7 / 12 page HC908JB16AD/D MC68HC08JB16 Addendum to MC68HC908JB16 Technical Data MC68HC08JB16 This section introduces the MC68HC08JB16, the ROM part equivalent to the MC68HC908JB16. The entire MC68HC908JB16 data book applies to this ROM device, with exceptions outlined below. MCU Block Diagram Figure 5 shows the block diagram of the MC68HC08JB16. Memory Map Figure 6 shows the memory map of the MC68HC08JB16. Reserved Registers The two registers at $FE08 and $FF09 are reserved locations on the MC68HC08JB16. On the MC68HC908JB16, these two locations are the FLASH control register and the FLASH block protect register respectively. Monitor ROM The monitor program (monitor ROM, $FE10–$FFCF) on the MC68HC08JB16 is for device testing only. Table 4.
