Wait State Configuration Register Setup:
DQ13, DQ12, DQ11 = “111” ⇒ Reserved
DQ13, DQ12, DQ11 = “110” ⇒ Reserved
DQ13, DQ12, DQ11 = “101” ⇒ 5 programmed, 7 total
DQ13, DQ12, DQ11 = “100” ⇒ 4 programmed, 6 total
DQ13, DQ12, DQ11 = “011” ⇒ 3 programmed, 5 total
DQ13, DQ12, DQ11 = “010” ⇒ 2 programmed, 4 total
DQ13, DQ12, DQ11 = “001” ⇒ 1 programmed, 3 total
DQ13, DQ12, DQ11 = “000” ⇒ 0 programmed, 2 total
Note:
“101”.
Note:
checking the status of the program or erase operation in the “busy” bank. The system should read status twice to ensure
valid information.

Figure assumes address DQ0 is not at an address boundary, active clock edge is rising, and wait state is set to
Breakpoints in waveforms indicate that system may alternately read array data from the “non-busy bank” while
