A six-word command (Enter Single Pulse Program Mode) sequence to remove the require-
ment of entering the three-word program sequence is offered to further improve programming
time. After entering the six-word code, only single pulses on the write control lines are required
for writing into the device. This mode (Single Pulse Word Program) is exited by powering
down the device, or by pulsing the RESET pin low for a minimum of 500 ns and then bringing
it back to V
not work while in this mode; if entered they will result in data being programmed into the
device. It is not recommended that the six-word code reside in the software of the final product
but only exist in external programming code.
