FLASH Memory
4.3 Functional Description
4.4 FLASH Control Register (FLCR)
Data Sheet
56
Address:
The FLASH memory is an array of 48,128 bytes with an additional 26
bytes of user vectors. An erased bit reads as logic 1 and a programmed
bit reads as a logic 0. Program and erase operations are facilitated
through control bits in a memory mapped FLASH control register
(FLCR). The address ranges for the user memory and vectors are:
Programming tools are available from Freescale . Contact your local
Freescale representative for more information.
The FLASH control register (FLCR) controls FLASH program and erase
operations.
