19.2.2.2 Program Page Buffers
MPC555
USER’S MANUAL
invalid (on-page reads) require one system clock. Read buffer management is trans-
parent to user software and is taken care of in hardware.
The CMF EEPROM modules A and B can program up to eight and six 64-byte pages
at one time, respectively. Each program page buffer is located in one program section.
All program page buffers within a CMF module share the same block offset address.
The block offset address is extracted from the address of the first programming write.
To select the CMF EEPROM array block that will be programmed, the program page
buffers use the CMF EEPROM array configuration and BLOCK[0:7].
The array block that will be programmed is selected by the BLOCK bit that is set. If
BLOCK[M] = 1 then program buffer[M] is active and array block[M] is selected for pro-
gramming.
Bits in the program page buffers select the non-program state if SES = 0. During a pro-
gram margin read, the program buffers update bits to the non-program state for bits
that correspond to array bits that the program margin read has determined are pro-
grammed.
