Analog Output Register Group

Two of the three registers making up the Analog Output Register Group load the two analog
output channels. DAC0 controls analog output channel 0. DAC1 controls analog output channel
1. These DACs are written to individually, and the analog output can be updated immediately or
each time an active low pulse is detected on the OUT2 bit of the Am9513A Counter/Timer. The
update method is selected with the LDAC bit in Command Register 2.
The third register in the Analog Output Register Group is the INT2CLR Register. The
AT-MIO-16D can be programmed to interrupt when it detects a rising edge signal on the OUT2
pin of the Am9513A Counter/Timer. This interrupt can be cleared by writing to the INT2CLR
Register.
Descriptions of the three registers making up the Analog Output Register Group are given on the
following pages.
