n Timing of Control Register
The internal registers are written by the 3-wire P interface pins: CSN, CCLK, CDTI. These data are included by Chip
Address (2bit, The AK5356 is fixed to “10”.), Read/Write (1bit), Address (MSB-first, 5bit) and Control data (MSB-first,
8bit). A side of transmitted data is output to each bit by “ ” of CCLK, a side of receiving data is input by “ ” of CCLK.
Writing of data becomes effective by “ ” of CSN. The clock speed of CCLK is 5MHz (max). The value of internal
registers is initialized at PDN pin = “L”.
