Serial Control Interface
(1) 3-wire Serial Control Mode (I2C pin = “L”)
Internal registers may be written via to the 3 wire P interface pins (CSN, CCLK and CDTI). The data on this interface
consists of Chip address (2bits, Fixed to “01”), Read/Write (1bit, Fixed to “1”, Write only), Register address (MSB first,
5bits) and Control data (MSB first, 8bits). Address and data is clocked in on the rising edge of CCLK. For write
operations, data is latched after a low-to-high transition of 16th CCLK. The clock speed of CCLK is 5MHz(max). The
value of internal registers is initialized at PDN pin = “L”.
