MOD2P: MOD2 DAC polarity. The MOD2 DAC (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 MOD2 DAC 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 2
APC2P: APC2 DAC polarity. The APC2 DAC (Table 02h, Registers CAh–CBh) 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 APC DAC
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
MOD1P: MOD1 DAC polarity. The MOD1 DAC (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 MOD1 DAC 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 0
APC1P: APC1 DAC polarity. The APC1 DAC (Table 02h, Registers CEh–CFh) 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 APC1
DAC 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.
