DAC2P: DAC2 VALUE polarity. The DAC2 VALUE (Table 02h, Registers C8h–C9h) range is
000h–3FFh. A setting of 000h creates a pulse-density of zero and 3FFh creates a pulse-density of
1023/1024. This polarity bit allows the user to use GND or VREFIN as the reference. The power-on
of DAC2 VALUE is 000h; thus an application that needs VREFIN to be the off state should use the
inverted polarity.
0 = Normal polarity. A setting of 000h results in a pulse-density output of zero held at GND, and a
setting of 3FFh results in a pulsed-density output of 1023/1024 held mostly at VREFIN.
1 = Inverted polarity. A setting of 000h results in a pulse-density output of zero held at VREFIN, and
a setting of 3FFh results in a pulsed-density output of 1023/1024 held mostly at GND.
BIT 1
DAC1P: DAC1 VALUE polarity. The DAC1 VALUE (Table 02h, Registers CCh–CDh) range is
000h–3FFh. A setting of 000h creates a pulse-density of zero and 3FFh creates a pulse-density of
1023/1024. This polarity bit allows the user to use GND or VREFIN as the reference. The power-on
of DAC1 VALUE is 000h; thus an application that needs VREFIN to be the off state should use the
inverted polarity.
0 = Normal polarity. A setting of 000h results in a pulse-density output of zero held at GND, and a
setting of 3FFh results in a pulsed-density output of 1023/1024 held mostly at VREFIN.
1 = Inverted polarity. A setting of 000h results in a pulse-density output of zero held at VREFIN, and
a setting of 3FFh results in a pulsed-density output of 1023/1024 held mostly at GND.
