Functional description

Read command format (Command 92 (memory residual read))

Read command format (Commands 90, 91, 93)

Microcontroller interface

Command format

Commands from the microcontroller are input using

3-wire serial interface inputs; data (YMDATA), bit

clock (YMCLK) and load signal (YMLD).

In the case of a read command from the microcon-

troller, bit serial data is output (ZSENSE) synchro-

nized to the bit clock input (YMCLK).

(M4 to M8 are always 0.)
