Section 20 ROM
20.8
A software method using the CPU is employed to program and erase flash memory in the on-
board programming modes. Depending on the FLMCR1 setting, the flash memory operates in one
of the following four modes: Program mode, program-verify mode, erase mode, and erase-verify
mode. The programming control program in boot mode and the user program/erase control
program in user program mode use these operating modes in combination to perform
programming/erasing. Flash memory programming and erasing should be performed in
accordance with the descriptions in section 20.8.1, Program/Program-Verify and section 20.8.2,
Erase/Erase-Verify, respectively.
