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 2-bit Chip address (Fixed to “10”), Read/Write (Fixed to “1”), Register address (MSB first, 5bits) 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”.
