(2) Control registers
The control registers can be set via the microcomputer interface in addition to the control pins.
These registers are consisted by 4 parts and each register is 8-bit.
For the value to be written in the control registers see the description of the interface with microcomputer.
The following describes the control register map
TEST: for TEST (input 0,X: it ignore input data, but should input 0).
