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(“
↓
”). CSN should be set to “H” once after 16 CCLKs for each address.
Clock speed of CCLK is 5MHz (max). The value of internal registers are initialized by PDN pin = “L”.
