Note: * The RTS instruction must not be used during the following periods.
Wait (Wait time = programming time)
Write pulse application subroutine
1. A period from programming 128-byte data to flash memory until clearing the P bit
2. A period from dummy-writing of H'FF to a verifying address until reading verifying data
