Alt. Pin
Func.:
The enable bit for IRQ is located in the DIOCTL register.
Port G is a fully bidirectional 8-bit port. Port G shares functions with the memory expansion address
lines and the external chip selects. Refer to 4 Memory Expansion and Chip Selects.
Always reads zero.
Overridden if corresponding interrupt request input is enabled.
0 = No interrupt pending for the corresponding interrupt line
1 = Interrupt pending for the corresponding interrupt line
0 = No interrupt pending for the corresponding interrupt line
1 = Interrupt pending for the corresponding interrupt line
0 = Interrupt request input is disabled and pin is controlled by DDRF bit
1 = Interrupt request input (IRQx) is enabled, overriding state of DDRF bit
0 = Input
1 = Output
