SERIAL INTERFACE
The internal registers can be read/written with SCLK, DATA, and CSN pins.
1word consists of 16bits. The first 4bits are the instruction code which specifies read/write.
The following 3bits specify the address. The rest of 8bits are for setting registers.

SCLK and WRITE/READ
(1) Input data are loaded into the internal shift register at the rising edge of SCLK.
(2) The rising edge of SCLK is counted after the falling edge of CSN.
(3) When CSN is “L” and more than 16 SCLK pulses:
[WRITE]
Data are loaded into the internal register at the rising edge of the SCLK 16
th
pulse.
[READ]
DATA pin is switched to an input pin at the falling edge of the SCLK 16
pulse.
CSN and WRITE / READ CANCELLATION
(1) WRITE is cancelled when CSN goes up before the rising edge of the SCLK 16
th
pulse.
(2) READ is cancelled when CSN goes up before the falling edge of the SCLK 16
th
pulse.
SERIAL WRITE / READ (SERIAL ACCESS)
(1) CSN must go up to “H” before the next access in successive access.
(2) When the next access is going to be done , if CSN remains to be “L”, successive access can not be done.
