17.7.4 Interrupt Flags

Name: INTFLAGS
Offset: 0x03
Reset: 0x00
Property: -

Access to the Virtual PORT registers has the same outcome as access to the regular registers but allows for memory-specific instructions, such as bit manipulation instructions, which cannot be used in the extended I/O Register space where the regular PORT registers reside.

Bit 76543210 
 INT[7:0] 
Access R/WR/WR/WR/WR/WR/WR/WR/W 
Reset 00000000 

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

Pin Interrupt Flag n is cleared by writing a ‘1’ to it.

Pin Interrupt Flag n is set when the change or state of pin n (Pxn) matches the pin’s Input/Sense Configuration (ISC) in PORTx.PINnCTRL.

Writing a ‘0’ to bit n in this bit field has no effect.

Writing a ‘1’ to bit n in this bit field will clear Pin Interrupt Flag n.
