Serial Control Interface
(1) 4-wire Serial Control Mode (I2C pin = “L”)
Internal registers may be written by using the 4-wire μP interface pins (CSN, CCLK, CDTI and CDTO). The data on this
interface consists of a 2-bit Chip address, Read/Write, Register address (MSB first, 5bits) and Control data (MSB first,
8bits). The chip address high bit is fixed to “1” and the lower bit is set by the CAD0 pin. Address and data is clocked in on
the rising edge of CCLK and data is clocked out on the falling edge. After a low-to-high transition of CSN, data is latched
for write operations and CDTO bit outputs Hi-Z. The clock speed of CCLK is 5MHz (max). The value of internal registers
is initialized at PDN pin = “L”.
