22.3.5.4
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 program 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 22.3.8 Full Status Check.)
An address that is already written cannot be altered or rewritten.
Figure 22.10 shows a Flow Chart of the Program Command Programming.
The lock bit protects each block from being programmed inadvertently. (Refer to 22.3.6 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 microcomputer 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 microcomputer 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.
