Serial Control Interface
1. 4 wire serial control mode (IICN pin = “H”)
With the 4-wire
μ
P interface pins (CSN, CCLK, CDTI and CDTO), the data on this interface consists of the Chip address
(2-bits, Fixed to “00”), Read/Write (1-bit), Register address (MSB first, 5-bits) and Control data (MSB first, 8-bits). The
data are clocked in on the rising edge of CCLK, and data are clocked out on the falling edge of CCLK. For write
operations, the data is latched after a low-to-high transition of the 16th CCLK. For read operation, the data is outputted to
Hi-Z on the rising edge of CSN. The clock speed of CCLK is 5MHz(max). The value of the internal registers is initialized
at PDN pin = “L”.
