PO DATA is synchronized with 2
cycle after reset, and the second data is out.
Selects total dot adjustment (8-bit, 3-bit and 5-bit) for
input data. Data is transferred to PI REG1 on 128
positive edge of PI CLK.
Holds the data transferred to PI REG1. Set is reflected
on all dot adjustment from the moment when it is held.
