Data Sheet — M68HC12B Family
The MC68HC12BE32 and MC68HC12BC32 contain 32 Kbytes of read-only
memory (ROM). The ROM array is arranged in a 16-bit configuration and may be
read as either bytes, aligned words or misaligned words. Access time is one bus
cycle for byte and aligned word access and two bus cycles for misaligned word
operations.
After reset, the ROM array is located from addresses $8000 to $FFFF in
single-chip mode. In expanded modes, the ROM array is located from address
$0000 to $7FFF; however, it is disabled from the memory map. The ROM can be
mapped to an alternate address range. See
