4.4 SETTING OF THE INTERNAL RESISTER
Initial setting of the internal Resister is undefined data. So the Resister Data must be written in the Resister,
after initialization by the /RESET pin. The Resister Data can be written from serial interface pins (/CS, SCL
and SI). The setting method is as follows.
(1) Command Byte Function

Note1: During 32-bit transfer of the Resister Data, /CS pin (Pin No.35) must be maintained active.
Note2: "X" is set in accordance with the usage conditions.
