26.3.2.4
The program command is used to write data to the flash memory in 16-bit units.
A program operation (program and verify data) starts by writing the command code xx40h in the first bus cycle
and data to the write address in the second bus cycle. 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 can be used to determine whether a program operation has been
completed or not. The FMR00 bit becomes 0 (busy) during the program operation and becomes 1 (ready) when
the program operation is completed.
After a program operation is completed, the FMR06 bit in the FMR0 register is used to determine whether a
program operation is completed successfully or not. (Refer to 26.3.5 Full Status Check for details.)
Do not execute the program command to the same address more than once without executing the block erase
command. Figure 26.9 shows a flow chart of the program command.
The lock bit can protect each block from being programmed inadvertently. (Refer to 26.3.3 Data Protect
Function for details.)
In EW1 mode, do not execute this command to the block where the rewrite control program is stored.
In EW0 mode, the flash memory enters read status register mode when a program operation starts.
