16.7.3

Input Value

Writing to the Virtual Port registers has the same effect as writing to the regular registers, but allows for

memory-specific instructions, such as bit-manipulation instructions, which are not valid for the extended

I/O memory space where the regular Port registers reside.

Bits 7:0 – IN[7:0]: Input Value

This bit field holds the value present on the pins if the digital input buffer is enabled.

Writing to a bit of VPORT.IN will toggle the corresponding bit in VPORT.OUT.

Interrupt Flag

Writing to the Virtual Port registers has the same effect as writing to the regular registers, but allows for

memory-specific instructions, such as bit-manipulation instructions, which are not valid for the extended

I/O memory space where the regular Port registers reside.w

Bits 7:0 – INT[7:0]: Interrupt Pin Flag

The INT flag is set when a pin change/state matches the pin's input sense configuration, and the pin is

configured as source for port interrupt.

Writing a '1' to this flag's bit location will clear the flag.

For enabling and executing the interrupt, refer to PORT_PINnCTRL.ISC.
