Serial Control Interface
The serial control interface is enabled by the P/S pin = “L”. The internal registers are written by the 3 wire uP interface
pins: CSN, CCLK, CDTI. The data on this interface consists of Chip address (2bits, fixed to C0/1 =”01”) Read/Write (1bit,
fixed to “1”. ), Register address (MSB first, 5bits) and Control data (MSB first, 8bits). Address and data is clocked in on
the rising edge of CCLK. Data is latched after a low-to-high transition of CSN. The maximum clock speed of the CCLK is
5MHz. The CSN should be “H” if no access. The chip address is fixed to “10”. Writing is invalid for the access to the chip
address except for “10”. PDN = “L” resets the registers to their default values.

When PDN = “L”, internal registers are initialized. In case of changing P/S pin, please set PDN = “L” to reset the device.
In case of serial mode, the internal timings are initialized by RSTN =”0”, but the contents of registers are hold.
