NOTE:
(FLCR)
The FLASH memory consists of an array of 12,288 bytes for user
memory plus a block of 38 bytes for user interrupt vectors and one byte
for the mask option register. 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:
Programming tools are available from Freescale. Contact your local
Freescale representative for more information.
A security feature prevents viewing of the FLASH contents.
1. No security feature is absolutely secure. However, Freescale’s strategy is to make reading or
copying the FLASH difficult for unauthorized users.
