Figure 21.8 Program Command
21.3.5.4 Program Command (40h)
The program command writes 2-byte data to the flash memory.
By writing xx40h in the first bus cycle and data to the write address in the second bus cycle, an
auto-program operation (data program and verify) will start. The address value specified in the first bus
cycle must be the same even address as the write address specified in the second bus cycle.
The FMR00 bit in the FMR0 register indicates whether an auto-program operation has been completed.
The FMR00 bit is set to 0 (busy) during auto-programming and to 1 (ready) when an auto-program
operation is completed.
After the completion of an auto-program operation, the FMR06 bit in the FMR0 register indicates
whether or not the auto-program operation has been completed as expected. (Refer to 21.3.8 Full
Status Check.)
An address that is already written cannot be altered or rewritten.
Figure 21.8 shows a flow chart of the Program Command.
The lock bit protects each block from being programmed inadvertently. (Refer to 21.3.6 Data Protect
Function.)
In EW1 mode, do not execute this command on the block where the rewrite control program is allocated.
In EW0 mode, the MCU enters read status register mode as soon as an auto-program operation starts.
The status register can be read. The SR7 bit in the status register is set to 0 at the same time an
auto-program operation starts. It is set to 1 when auto-program operation is completed. The MCU remains in
read status register mode until the read array command is written. After completion of an auto-program
operation, the status register indicates whether or not the auto-program operation has been completed
as expected.
