Chapter 28 Flash Memory Module (FTFL)
Upon clearing CCIF to launch the Program Longword command, the FTFL programs the
data bytes into the flash using the supplied address. The swap indicator address in each
program flash block is implicitly protected from programming. The targeted flash
locations must be currently unprotected (see the description of the FPROT and FDPROT
registers) to permit execution of the Program Longword operation.
The programming operation is unidirectional. It can only move NVM bits from the erased
state ('1') to the programmed state ('0'). Erased bits that fail to program to the '0' state are
flagged as errors in MGSTAT0. The CCIF flag is set after the Program Longword
operation completes.
The supplied address must be longword aligned (flash address [1:0] = 00):
• Byte 0 data is written to the supplied address ('start'),
• Byte 1 data is programmed to byte address start+0b01,
• Byte 2 data is programmed to byte address start+0b10, and
• Byte 3 data is programmed to byte address start+0b11.
