7.3.2.2
This register is reserved.
Read: always read $00
Write: unimplemented
7.3.2.3
Read: read zeroes when DJM is set
Write: unimplemented when DJM is set
The DAC data register is an 8-bit readable/writable register that stores the data to be converted when DJM
bit is clear. When the DACE bit is set, the value in this register is converted into an analog voltage such
that values from $00 to $FF result in equal voltage increments from V
this register reads zeroes and cannot be written.
