normal path, the WDT counter will not be cleared and reset signal will be generated.
WDT is the enabling signal generated by calculating 32768-clock overflow. Reset Register content is
same as TC1 (Timer1 clock), which uses the same clock count source. WDT function can be generated in
Normal, Slow and Idle Mode. However, WDT will not function during Sleep Mode (as the TC1 clock has
stopped.)

Digital-to-Analog Converter
The Digital-to-Analog converter (DAC) converts 7-bit unsigned speech data written to PWMC data
register to proportional current.

There are two output paths for the DAC. Either VO or DAO can be selected as output port of DAC by
VOC register when it is enabled. The VO output is primarily intended for speech generation, although it
is not necessary so, while the DAO output path can be used in conjunction with built-in OP comparator to
function as an Analog-to-Digital Converter as required in applications such as speech recording, speech
recognition or sensor interfaces.

The DAC is enabled by DAC bit of VOC register. Please note that the DAC bit of VOC register will be
automatically cleared when the system enter Idle or Sleep mode. So it needs to be set again when
returning to Normal mode.
