Output timing of decode data
(1)
(2) Outputs decode data in 16 clocks of the SCK after switching over

(4) If no data are present, or if data have already been read, 0000
Fig. 11 Decode data output timing
The 16 bits in the SCK after the CS signal has fallen are the ad-
dress, and for succeeding input data, the address is incremented
every 16 bits.
Setting “1” in the W/R register activates output mode.

Raising the CS signal deactivates output mode.
(To switch over to input mode, cause CS to fall.)
