Monitor ROM (MON)
8.5.7 EE_READ
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 7 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
EE_WRITE). It loads the 15-byte data set stored in the $EE00–$EFFF page to the data array in RAM.
The initialization subroutine is the same as the coding example for EE_WRITE (see

1. The start address must be a page boundary start address.
The EE_READ routine is unable to check for incorrect data blocks, such as
the FLASH page boundary address and data size. It is the responsibility of
the user to ensure the starting address indicated in the data block is at the
FLASH page boundary and the data size is 7 to 15. If the FLASH page is
programmed with a data array with a different size, the EE_READ call will
be ignored.
