GPIO Interrupt Polarity 5-0 (GPIO_INT_POL[5:0])
These bits set the interrupt polarity of the GPIO pins. The configured level
(high/low) will set the corresponding GPIO_INT bit in the
I/O Interrupt Status and Enable Register
0: Sets low logic level trigger on corresponding GPIO pin
1: Sets high logic level trigger on corresponding GPIO pin
RESERVED
GPIO Buffer Type 5-0 (GPIOBUF[5:0])
This field sets the buffer types of the GPIO pins.
0: Corresponding GPIO pin configured as an open-drain driver
1: Corresponding GPIO pin configured as a push/pull driver
As an open-drain driver, the output pin is driven low when the corresponding
data register is cleared, and is not driven when the corresponding data
register is set.
GPIO/LED
This section details the General Purpose I/O (GPIO) and LED related System CSR’s.
General Purpose I/O Configuration Register (GPIO_CFG)
This read/write register configures the GPIO input and output pins. The polarity of the GPIO pins is
configured here.
