Interface
The internal registers may be either written or read by the 4-wire μP interface pins: CSN, CCLK, CDTI & CDTO. The
data on this interface consists of Chip address (2bits, C0/1 are fixed to “00”), Read/Write (1bit), Register address (MSB
first, 5bits) and Control data (MSB first, 8bits). Address and data is clocked in on the rising edge of CCLK and data is
clocked out on the falling edge. For write operations, data is latched after the 16th rising edge of CCLK, after a
high-to-low transition of CSN. For read operations, the CDTO output goes high impedance after a low-to-high transition
of CSN. The maximum speed of CCLK is 5MHz. The CSN and CCLK must be fixed to “H” when the register does not
be accessed. PDN= “L” resets the registers to their default values. When the state of P/S pin is changed, the AK4112A
should be reset by PDN= “L”.
