8. The maximum number of repetitions of the program/program-verify sequence of the same bit
is 1,000.
Note: *The RTS instruction must not be used during the following 1. and 2. periods.
Wait (Wait time=programming time)
1. A period between 128-byte data programming to flash memory and the P bit clearing
2. A period between dummy writing of H'FF to a verify address and verify data reading
