BIAS MODE Canceling State (SERIAL communication)

The POWER ON RESET state from the BIAS MODE covers the period from the rise of C.S

for communication of

canceling of the BIAS MODE to the second rise

of CS input after the fall

of POWER ON PULSE

generated inside

IC.

is the dummy communication.

Actually, because of delay of several hundreds ns in the IC, the first DATA condition begins in

and the normal

SERIAL communication condition begins after

.
