Note: 1. When the PLL divisor has its standard value (PLL4:0 = 10110).
2. Target values are shown. (The number of horizontal bits varies with, for example, the frame width adjustment.)
Initialization
(1) RES pin: Reset
The RES pin must be held low when power is first applied with the timing shown in the figure.
(2) Internal control registers
After a reset, the chip goes to the standby state (SBY = high). When developing the microcontroller software, that
software must be designed so that it transmits data for all registers. Also note that data values of zero (0) must be sent
for the control registers that have ‘0’ entries in the control register table.
