SM5905AF
Write command format (Commands 80 to 86)
SM5905AF has two modes of operation; shock-
proof mode and through mode.
The operating sequences are controlled using com-
mands from a microcontroller.

Functional description
Read command format (Command 92 (memory residual read))
Read command format (Commands 90, 91, 93)
Microcontroller interface
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).
Write command format (Commands 87)
