17.2 Register Descriptions
17.2.1 D/A Data Registers 0 and 1 (DADR0, DADR1)
Bit:76543210
Initial value : 0 0 0 0 0 0 0 0
R/W : R/W R/W R/W R/W R/W R/W R/W R/W
DADR0 and DADR1 are 8-bit readable/writable registers that store data for conversion.
Whenever output is enabled, the values in DADR0 and DADR1 are converted and output from the analog output pins.
DADR0 and DADR1 are each initialized to H'00 by a reset and in hardware standby mode.
17.2.2 D/A Control Register (DACR)
Bit:76543210
DAOE1 DAOE0 DAE
Initial value : 0 0 0 1 1 1 1 1
R/W : R/W R/W R/W
DACR is an 8-bit readable/writable register that controls the operation of the D/A converter.
DACR is initialized to H'1F by a reset and in hardware standby mode.
Bit 7—D/A Output Enable 1 (DAOE1): Controls D/A conversion and analog output for channel 1.
Bit 7
DAOE1 Description
0 Analog output DA1 is disabled (Initial value)
1 Channel 1 D/A conversion is enabled; analog output DA1 is enabled
Bit 6—D/A Output Enable 0 (DAOE0): Controls D/A conversion and analog output for channel 0.
Bit 6
DAOE0 Description
0 Analog output DA0 is disabled (Initial value)
1 Channel 0 D/A conversion is enabled; analog output DA0 is enabled
