(4) The memory address is transferred in the 2nd cycle. Do not transfer addresses in the 3rd or
later cycles.
(5) Do not issue commands while programming is in progress.
(6) When programming, execute automatic programming once for each 128-byte block of
addresses. Programming the block at an address where programming has already been
performed is not possible.
(7) To confirm the end of automatic programming, check the signal on the I/O
in the status-read mode is also possible (status polling of the I/O
status of automatic programming).
(8) Status-polling information on the I/O
written. As long as no command is written, the information is made readable by setting CE and
OE for enabling.
For the AC characteristics in auto-program mode, see section 17.29.2, AC Characteristics and
Timing in PROM Mode.

17.28.5 Auto-Erase Mode

(1) Auto-erase mode only supports erasing of the entire memory.
(2) Do not perform command writing during auto erasing is in progress.
(3) To confirm the end of automatic erasing, check the signal on the I/O
status-read mode is also possible (status polling of the I/O
of automatic erasure).
(4) Status polling information on the I/O
As long as no command is written, the information is made readable by setting CE and OE for
enabling.
For the AC characteristics in auto-erase mode, see section 17.29.2, AC Characteristics and Timing
in PROM Mode.

17.28.6 Status-Read Mode

(1) Status-read mode is used to determine the type of an abnormal termination. Use this mode
when automatic programming or automatic erasure ends abnormally.
(2) The return code is retained until writing of a command that selects a mode other than status-
read mode.
Table 17-59 lists the return codes of status-read mode.
For the AC characteristics in status-read mode, see section 17.29.2, AC Characteristics and
Timing in PROM Mode.
