17.28.8 Time Taken in Transition to PROM Mode
Until oscillation has stabilized and while PROM mode is being set up, the LSI is unable to accept
commands. After the PROM-mode setup time has elapsed, the LSI enters memory-read mode. See
section 17.29.2, AC Characteristics and Timing in PROM Mode.
17.28.9 Notes on Using PROM Mode
(1) When programming addresses which have previously been programmed, apply auto-erasing
before auto-programming.
(2) When using PROM mode to program a chip that has been programmed/erased in an on-board
programming mode, auto-erasing before auto-programming is recommended.
