(First DATA hold)

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

canceling of the BIAS MODE to the second rise g of CS input after the fall e of POWER ON PULSE d generated inside

IC. f is the dummy communication.

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

SERIAL communication condition begins after h.
