DESCRIPTION
DAC Load Strobe, rising-edge triggered.
Reset, rising-edge triggered. Depending on the state
of RSTSEL, the DAC registers are set to either mid-
scale or zero.
Reset Select. Determines the action of RST. If
HIGH, a RST command will set the DAC registers to
mid-scale. If LOW, a RST command will set the DAC
registers to zero.
