Serial Control Interface
(1) 3-wire Serial Control Mode (I2C pin = “L”)
Internal registers may be written by using the 3-wire μP interface pins (CSN, CCLK and CDTI). The data on this interface
consists of a 1-bit Chip address (Fixed to “1”), Read/Write (Fixed to “1”), Register address (MSB first, 6bits) and Control
data (MSB first, 8bits). Each bit is clocked in on the rising edge (“
”) of CCLK. Address and data are latched on the 16th
CCLK rising edge (“
”) after CSN falling edge(“
”). Clock speed of CCLK is 5MHz (max). The value of internal
registers are initialized by PDN pin = “L”.
