Section 20 Flash Memory (0.35-μm F-ZTAT Version)
20.7
A software method, using the CPU, is employed to program and erase flash memory in the on-
board programming modes. Depending on the FLMCR1 and FLMCR2 setting, the flash memory
operates in one of the following four modes: program mode, erase mode, program-verify mode,
and erase-verify mode. The programming control program in boot mode and the user
program/erase program in user 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 20.7.1, Program/Program-Verify and section 20.7.2,
Erase/Erase-Verify, respectively.
20.7.1
When programming data or programs to the flash memory, the program/program-verify flowchart
shown in figure 20.7 should be followed. Performing programming operations according to this
flowchart will enable data or programs to be programmed to the flash memory without subjecting
the chip to voltage stress or sacrificing program data reliability.
1. Programming must be done to an empty address. Do not reprogram an address to which
2. Programming should be carried out 128 bytes at a time. A 128-byte data transfer must be
3. Prepare the following data storage areas in RAM: a 128-byte programming data area, a 128-
4. Consecutively transfer 128 bytes of data in byte units from the programming data area,
5. The time during which the P bit is set to 1 is the programming time. Figure 20.7 shows the
6. The watchdog timer (WDT) is set to prevent overprogramming due to program runaway, etc.
