a. When EKA8566A sends command/data to

CID, CRS is used to indicate if CID receives

the command/data. CRS is asserted after

CLK is asserted, CRS is de-asserted after

CLK is de-asserted. If CRS is not asserted,

then indicate that CID does not receive

CRS

I

command/data.

−

b. When CID requests to send command/data

to EKA8566A, CRS will be asserted. CLK is

asserted after CRS is asserted, CLK is

de-asserted after CRS is de-asserted. If

CLK is not asserted, then indicate that the

EKA8566A does not receive

command/data.

CID_PWR I

CID_PWR=0: CID is in power down

−

CID_PWR=1: CID is in power on

Note: I – signal is from CID to eKA8566A.

O – signal is from eKA8566A to CID.
