This section describes the Flash EEPROM module which is a 64k byte
Flash (Non-Volatile) Memory. The Flash array is organized as 2 blocks
of 32k bytes. Each block is organized as 512 rows of 64 bytes. The Flash
block’s erase sector size is 8 rows (512 bytes).
The Flash memory may be read as either bytes, aligned words or
misaligned words. Read access time is one bus cycle for byte and
aligned word, and two bus cycles for misaligned words.
Program and erase functions are controlled by a command driven
interface. Both sector erase and mass erase of the entire 64k byte Flash
block are supported. An erased bit reads ‘1’ and a programmed bit reads
