Description of Operation
STB, CK and DIN.
on the rising edge of STB. The operation mode is determined by the combination of the W/R signal and the OP code.
The operations listed below in the Operation mode selection table are performed using the five pins V.P, W/R,
All operations modes other than Normal Operation Mode are triggered by 8-bit serial data input on DIN and CK

Input of an OP code (DI1 = H, A6~A0 = address of word to be written) on DIN (while 18 V is applied to
Note that if D0~D7 are all High, a Byte Erase (all bits are set to H) is performed.
The write starts on the falling edge of the 16
During a write, DOUT is High-Impedance.
