10.6.8 EE_READ
MC68HC908LJ24/LK24 — Rev. 2.1
Freescale Semiconductor
EE_READ is used to load the data array in RAM with a set of data from
FLASH.
The EE_READ routine reads data stored by the EE_WRITE routine. An
EE_READ call will retrieve the last data written to a FLASH page and
loaded into the data array in RAM. Same as EE_WRITE, the data size
indicated by DATASIZE is 2 to 15, and the start address
ADDRH:ADDRL must the FLASH page boundary address.
The coding example below uses the data stored by the EE_WRITE
coding example (see
stored in the $EF00–$EE7F page to the data array in RAM. The
initialization subroutine is the same as the coding example for
EE_WRITE (see
