7.2.7 Erase / Program Resume (7Ah)

The Erase / Program Resume command “7Ah” must be written to resume the Sector or Block Erase

operation or the Page Program operation after an Erase / Program Suspend. The Resume command “7Ah”

will be accepted by the device only if the SUS bit in the Status Register equals to 1 and the BUSY bit equals to

0. After the Resume command is issued the SUS bit will be cleared from 1 to 0 immediately, the BUSY bit will

be set from 0 to 1 within 200 ns and the Sector or Block will complete the erase operation or the page will

complete the program operation. If the SUS bit equals to 0 or the BUSY bit equals to 1, the Resume command

“7Ah” will be ignored by the device. The Erase / Program Resume command sequence is shown in Figure

7.12. It is required that a subsequent Erase / Program Suspend command not to be issued within a minimum

of time of “tSUS” following a Resume command.

7.3 Read Commands

7.3.1 Read Data (03h)

The Read Data instruction allows one more data bytes to be sequentially read from the memory. The

instruction is initiated by driving the CS# pin low and then shifting the instruction code “03h” followed by a
