17.2
17.2.1
DADR0 to DADR3 are 8-bit readable/writable registers that store data for conversion.
Whenever output is enabled, the values in DADR0 to DADR3 are converted and output from the
analog output pins.
DADR0 to DADR3 are each initialized to H'00 by a reset and in hardware standby mode.
17.2.2
DACR01 and DACR23 are 8-bit readable/writable registers that control the operation of the D/A
converter.
DACR01 and DACR23 are each 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.
