c interface (CSDA, CSCL) on the MT8293 is a slave interface capable of running
up to 400KHZ. This bus is used to configure the MT8293 by reading/writing to the appropriate
registers. The MT8293 is accessible on the local I
2
c bits at two-device address. The logic state of
the CI2CA pin is latched on the rising edge of REST# providing a choice of two pairs of device
address.
