80C51 with 256 B RAM, 192 B data EEPROM
Writing either the PROG or EP command to FMCON will start the program or
erase-program process and place the CPU in a program-idle state. The CPU will remain
in this idle state until the program or erase-program cycle is completed. Interrupts will NOT
be serviced until the cycle is completed.
Erase-program or programming of a single byte (or multiple bytes) in the data EEPROM
array is accomplished using the following steps:
Write the LOAD command (00H) to FMCON. The LOAD command will clear all
locations in the page register and their corresponding update ags.
Write the address within the page register to FMADRL. Since the loading the page
register uses FMADRL[5:0], and since the erase-program or program command uses
FMADRH and FMADRL[7:6], the user can write the byte location within the page
register (FMADRL[5:0]) and the code memory page address (FMADRH and
FMADRL[7:6]) at this time.
Write the data to be programmed to FMDATA. This will increment FMADRL pointing to
the next byte in the page register.
Write the address of the next byte to be programmed to FMADRL, if desired. (This is
not needed for contiguous bytes since FMADRL is auto-incremented). All bytes to be
programmed must be within the same page.
Write the data for the next byte to be programmed to FMDATA.
Repeat writing of FMADRL and/or FMDATA until all desired bytes have been loaded
into the page register.
Write the page address mapped into user code memory to FMADRH and
FMADRL[7:6], if not previously included when writing the page register address to
FMADRL[5:0].
Write the EP (68H) or PROG (48H) command to FMCON, starting the erase-program
or program cycle.
Read FMCON to check status. If aborted, repeat starting with the LOAD command.
