NOTE:
(FLBPR)
Register
(FLCR)
The FLASH memory consists of an array of 12,288 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:
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.
