Pin Function
(1) Input clock up to 5MHz in SPI slave mode; (2) output clock at 61kHz
in I
(1) Serial data input in SPI slave mode; (2) serial data input/output in
I
(1) SPI serial data output in SPI slave mode; (2) output clock at 61kHz
in I
Active low. (1) SPI data transfer start in SPI slave mode. When SPIS_N
is high, the KS8995MA/FQ is deselected and SPIQ is held in high
impedance state, a high-to-low transition to initiate the SPI data
transfer; (2) not used in I
