ta and protect bits are erased normally. If necessary, execute the automatic protect bit erase, automat-
ic chip erase or automatic block erase.

22.2.5.6 ID-Read
(1) Operation Description
The ID-Read command can read information including Flash memory type and three types of co-
des such as a maker code, device code and macro code.
(2) How to Set
The 1st to 3rd bus write cycles indicate the ID-Read command. In the 4th bus write cycle, the
code to be read is specified. After the 4th bus write cycle, read operation in the arbitrary flash area ac-
quires codes.
The ID-Read can be executed successively. The 4th bus write cycle and reading ID value can be exe-
cuted repeatedly.
The ID-Read command does not automatically return to the read mode. To return to the read
mode, execute the read command, read/reset command or hardware reset.

(1) Operation Description
A command to return Flash memory to the read mode.
When the ID-Read command is executed, macro stops at the current status without automatically re-
turn to the read mode. To return to the read mode from this situation, use the read command or read/
reset command. It is also used to cancel the command when commands are input to the middle.
(2) How to Set
The 1st bus cycle indicates the read command. The 1st to 3rd bus write cycles indicate the read/re-
set command. After either command sequence is executed, Flash memory returns to the read mode.
