3.9.6 POLARITY_CTRL Register (Address = 1F9h) [reset = X]
POLARITY_CTRL is shown in
and described in
Return to
Polarity control register. This register allows to invert the initial polarity of the input or output pin.
RESET register domain: HWRST
Note: It is user responsibility to take care about the pull-up/pull-down selections versus the IO polarity

Description
7
INT_POLARITY
R/W
X
Select the polarity of the INT output line
0: Interrupt line (INT) is low when interrupt is pending (default)
1: Interrupt line (INT) is high when interrupt is pending
6
GPIO_6_POLARITY
R/W
X
Select the polarity of the GPIO_6 input or output lines and
associated secondary functions
0: inversion not enable - active high (default)
1: inversion is enabled - active low
In case NSLEEP input line is selected as secondary function:
0: Resources will go in SLEEP mode when NSLEEP is low (default)
1: Resources will go in SLEEP mode when NSLEEP is high
5
GPIO_5_POLARITY
R/W
X
Select the polarity of the GPIO_5 input or output lines and
associated secondary functions
0: inversion not enable - active high (default)
1: inversion is enabled - active low
4
GPIO_4_POLARITY
R/W
X
Select the polarity of the GPIO_4 input or output lines and
associated secondary functions
0: inversion not enable - active high (default)
1: inversion is enabled - active low
3
GPIO_3_POLARITY
R/W
X
Select the polarity of the GPIO_3 input or output lines and
associated secondary functions
0: inversion not enable - active high (default)
1: inversion is enabled - active low
In case ENABLE1 input line is selected as secondary function:
0: Resources will be enable when ENABLE1 is high (default)
1: Resources will be enable when ENABLE1 is low
2
GPIO_2_POLARITY
R/W
X
Select the polarity of the GPIO_2 input or output lines and
associated secondary functions
