***8211; MC68HC908LJ24 mask set 0L83S
Note:
The mask set is identified by a 5-character code consisting of a version number,
a letter, two numerical digits, and a letter, for example 0L83S.
All standard devices are marked with a mask set number and a date code.
FLASH memory consists of an array of 24,576 bytes for user memory plus a
block of 48 bytes for user interrupt vectors. An erased bit reads as logic 1 and
a programmed bit reads as a logic 0. The FLASH memory page size is defined as
128 bytes, and is the minimum size that can be erased in a page erase operation.
Program and erase operations are facilitated through control bits in FLASH
control register (FLCR). The address ranges for the FLASH memory are:
***8226; $9000***8211;$EFFF; user memory, 24,576 bytes
***8226; $FFD0***8211;$FFFF; user interrupt vectors, 48 bytes3
