Description
41
RWCK
(Read/Write Clock) Connected to the RWCK pin of the serial register.
O Clock pin for reading and writing data to the serial registers.
40
WE
(Write Enable) Connected to the WE pin of serial register. The pin
O
to select read or write mode.
(Data I/O) Connected to the DIN and DOUT pins of serial register.
36
DI/O
I/O Data input and output mode.
(Chip Select) Connected to the CS pin of the serial register.
CS3 pin and CS4 pin have different functions depending on the
number of serial registers to be connected. The number of serial
registers is selected by the RSEL1 and RSEL2 pins.
CS3 (STBY) pin becomes CS3 when four serial registers are used\,

CS3 (STBY) O otherwise it is the RSEL0-pin used to select the number of serial
35
CS4 (RSEL0) I/O registers used.
