17.3 Registers and Register Details

17.3.1 DAT0/1 ( D/A data register)

D/A converter data register 1
Address : 00003B
Read/write
Initial value
D/A converter data register 0
Address : 00003A
Read/write
Initial value
[bits 15 to 8] DA17 to DA10
These bits are used to set the output voltage of D/A converter ch1.
These bits are not initialized upon a reset. These bits are readable and writable.
[bits 7 to 0] DA07 to DA00
These bits are used to set the output voltage of D/A converter ch0.
These bits are not initialized upon a reset. These bits are readable and writable.

17.3.2 DACR0/1 ( D/A control register)

D/A control register 1
Address : 00003D
Read/write
Initial value
D/A control register 0
Address : 00003C
Read/write
Initial value
[bit 0] DAE1 and DAE0
These bits are used to enable or disable the D/A converter output. DAE1 controls channel 1 output,
while DAE0 controls channel 0 output.
When '1' is written to these bits, D/A output is enabled. When '0' is set, D/A output is disabled.
These bits are initialized to '0' upon a reset. These bits are readable and writable.
