16.4 D/A Converter Operations

(1) Select the channel 0 operating mode and channel 1 operating mode with DAM4 and DAM5, respectively,
of the D/A converter mode register (DAM).
(2) Set the data corresponding to the analog voltages output to the ANO0/P130 and ANO1/P131 pins to the
D/A conversion value setting registers 0 and 1 (DACS0 and DACS1), respectively.
(3) Start the channel 0 and channel 1 D/A conversion operations by setting DACE0 and DACE1, respectively,
of the DAM.
(4) In the normal mode, the analog voltage signals are output to the ANO0/P130 and ANO1/P131 pins
immediately after the D/A conversion. In the real-time output mode, the analog voltage signals are output
synchronously with the output triggers.
(5) In the normal mode, the analog voltage signals to be output are held until new data are set in DACS0 and
DACS1. In the realtime output mode, new data are set in DACS0 and DACS1 and then they are held until
the next trigger is generated.
Caution Set DACE0 and DACE1 after setting data in DACS0 and DACS1.
