4.9 Programming procedure for circuit C. The waveforms on figure 5C, the programming characteristics in
table IVC and the following procedures shall apply for programming the device:
a. Connect the device in the electrical configuration for programming.
b. Terminate all device outputs with a 10 k Ω resistor to V
c. Address the PROM with the binary address of the selected word to be programmed. Raise V
d. After a t
e. After a t
f. After a t
g. Other bits in the same word may be programmed sequentially while the V
h. Repeat 4.9c through 4.9g for all other bits to be programmed.
