BA + 0x408h (1032): DAC3 Update Register (Write)
16-bit Operation. A write to this register will load the value into DAC3 and automatically update the DAC when
bit 8 of BA + 0x400h is set to 0.

BA + 0x40Ah (1034): DAC4 Update Register (Write)
16-bit Operation. A write to this register will load the value into DAC4 and automatically update the DAC when
bit 8 of BA + 0x400h is set to 0.

BA + 0x410h (1040): Analog Threshold Detector Setup (Read/Write)
16-bit Operation. The Threshold Trigger Level value (bits 7 to 0) can be anything between 0x00h and 0xFFh.
Refer to Analog Trigger on page 80 for further information and corresponding voltage values for each
hexadecimal number.

Trigger On
0 = A/D value < threshold
1 = A/D value > threshold
Use Threshold
0 = Do not use analog trigger
1 = use analog trigger
Read: Bit 15 = reserved
