3-2. Data input mode selection and signal specifications
The following three methods can be used for the parallel input data input method.
1) 16-bit with strobe
2) 8-bit multiplexed with strobe
3) 16-bit sample
These methods are selected with parameter No. C32-0.
(1) 16-bit with strobe (C32-0 = 1)
The 16-bit data (D0 to 15) is loaded with the rising edge of the strobe (STB).

(2) 8-bit multiplexed with strobe (C32-0 = 2)
The 16-bit data is divided into the low-order 8-bit and high-order 8-bit with the LSB signal, and
each is loaded with the rising edge of the strobe (STB).
