7-1. Microcomputer interface
Each mode can be set by inputting the 16-bit data (D15 to D0) and 8-bit command (B7 to B0) starting
from the MSB in 3 inputs of MDATA, MCLK, and MLD at the timing as shown in Figure 7-1-1.

Noteʣɾ Data is determined at the "L" level of MLD.
ɾ MDATA, MCLK, and MLD are invalid while NRST is "L."
ɾ All commands are initialized by setting NRST to "L."
ɾ While MLD is set to "L," MCLK will be canceled if it rises.
ɾ Set 0 to any bit which is input through the MDATA input with no functional
specification assigned to the bit.
