6.7.2 Program-Verify
Mode
In program-verify mode, the data written in program mode is read to check whether it has been
correctly written in the flash memory.
After the elapse of the programming time, exit programming mode (clear the P bit to 0) and select
program-verify mode (set the PV bit to 1). In program-verify mode, a program-verify voltage is
applied to the memory cells at the latched address. If the flash memory is read in this state, the
data at the latched address will be read. After selecting program-verify mode, wait at least 4 µs
before reading, then compare the programmed data with the verify data. If they agree, exit
program-verify mode and program the next address. If they do not agree, select program mode
again and repeat the same program and program-verify sequence. Do not repeat the program and
program-verify sequence more than six times* for the same bit.
Note: * When a bit is programmed repeatedly, set a loop counter so that the total programming
time will not exceed 1 ms.
