121 / 492 page ![]() 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. Name: IN Offset: 0x02 Reset: 0x00 Property: - Bit 7 6 5 4 3 2 1 0 IN[7:0] Access R/W R/W R/W R/W R/W R/W R/W R/W Reset 0 0 0 0 0 0 0 0 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. 16.7.4 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 Name: INTFLAGS Offset: 0x03 Reset: 0x00 Property: - Bit 7 6 5 4 3 2 1 0 INT[7:0] Access R R R R R R R R Reset 0 0 0 0 0 0 0 0 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. ATtiny417/817 © 2017 Microchip Technology Inc.
