12.2 Register Descriptions
12.2.1 D/A Data Registers 0 and 1 (DADR0, DADR1) H'FFA8, H'FFA9
Bit:76543210
Initial value:00000000
Read/Write: R/W R/W R/W R/W R/W R/W R/W R/W
D/A data registers 0 and 1 (DADR0 and DADR1) are 8-bit readable and writable registers that
store data to be converted. When analog output is enabled, the value in the D/A data register is
converted and output continuously at the analog output pin.
The D/A data registers are initialized to H'00 at a reset and in the standby modes.

DAOE1 DAOE0 DAE
Initial value:00011111
Read/Write: R/W R/W R/W
The D/A control register is an 8-bit readable and writable register that controls the operation of the
D/A converter module.
The D/A control register is initialized to H'1F at a reset and in the standby modes.
