This section describes the operation of the embedded FLASH memory.
This memory can be read, programmed, and erased from a single
external supply. The program and erase operations are enabled through
the use of an internal charge pump.
The MC68HC908LD64 FLASH memory contains two arrays:
An additional 32 bytes of FLASH user vectors, $FFE0–$FFFF, are in the
same array as the 47,616-byte. The size, address range, and memory
usage of the arrays are summarized in
An erased bit reads as logic 1 and a programmed bit reads as logic 0.
