AIN4 Register MSBs (Read) [Address = 0Bh]
This 8-bit read register contains the eight MSBs of the AIN4
analog input voltage word. The value in this register is com-
bined with Bits D6:7 of the external temperature value and
Analog Inputs 1 to 4 register LSBs, Address 04h, to give the full
10-bit conversion result of the analog value on the AIN4 pin.

DAC A Register (Read/Write) [Address = 11h]
This 8-bit read/write register contains the eight bits of the DAC
A word. The value in this register is converted to an analog
voltage on the VOUT-A pin. On power-up, the voltage output on
the VOUT-A pin is 0 V.
