Section 17 D/A Converter
17.2.3
MSTPCR is a 16-bit readable/writable register that performs module stop mode control.
When the MSTP10 bit in MSTPCR is set to 1, D/A converter operation stops at the end of the bus
cycle and a transition is made to module stop mode. Registers cannot be read or written to in
module stop mode. For details, see section 21.5, Module Stop Mode.
MSTPCR is initialized to H'3FFF by a reset and in hardware standby mode. It is not initialized in
software standby mode.
Bit 10—Module Stop (MSTP10): Specifies the D/A converter channel 0 and 1module stop
mode.

17.3
The D/A converter includes D/A conversion circuits for two channels, each of which can operate
independently.
D/A conversion is performed continuously while enabled by DACR. If either DADR0 or DADR1
is written to, the new data is immediately converted. The conversion result is output by setting the
corresponding DAOE0 or DAOE1 bit to 1.
The operation example described in this section concerns D/A conversion on channel 0. Figure
17.2 shows the timing of this operation.
[1] Write the conversion data to DADR0.
