DAC input register load control, active low
DAC register load control, 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, an RST command sets the DAC
registers to mid-scale (8000h). If low, an RST
command sets the DAC registers to zero
(0000h).
