Table 9-1. GPIO Port Output Control Truth Table and Interrupt Polarity
Q1, Q2, and Q3 discussed below are the transistors referenced in Figure 9-2. The available GPIO drive strength are:
9.2
Each GPIO pin can be individually enabled or disabled as an interrupt source. The Port 0–3 Interrupt Enable Registers provide
this feature with an Interrupt Enable bit for each GPIO pin.
During a reset, GPIO interrupts are disabled by clearing all of the GPIO Interrupt Enable bits. Writing a ‘1’ to a GPIO Interrupt
Enable bit enables GPIO interrupts from the corresponding input pin. All GPIO pins share a common interrupt, as discussed in
Section 14.7
.

• Output LOW Mode: The pin’s Data Register is set to ‘0.’
• Output HIGH Mode: The pin’s Data Register is set to 1 and the Port Configuration Bits[1:0] is set to ‘10.’
• Resistive Mode: The pin’s Data Register is set to 1 and the Port Configuration Bits[1:0] is set to ‘11.’
• Hi-Z Mode: The pin’s Data Register is set to1 and Port Configuration Bits[1:0] is set either ‘00’ or ‘01.’
Writing ‘0’ to the pin’s Data Register puts the pin in output LOW mode, regardless of the contents of the Port Configuration
Bits[1:0]. In this mode, Q1 and Q2 are OFF. Q3 is ON. The GPIO pin is driven LOW through Q3.
In this mode, Q1 and Q3 are OFF. Q2 is ON. The GPIO is pulled up through Q2. The GPIO pin is capable of sourcing... of
current.
Q2 and Q3 are OFF. Q1 is ON. The GPIO pin is pulled up with an internal 14k resistor. In resistive mode, the pin may serve
as an input. Reading the pin’s Data Register returns a logic HIGH if the pin is not driven LOW by an external source.
Q1, Q2, and Q3 are all OFF. The GPIO pin is not driven internally. In this mode, the pin may serve as an input. Reading the
Port Data Register returns the actual logic value on the port pins.
