INT2IP: INT2 External Interrupt Priority bit
1 = High priority
0 = Low priority
INT1IP: INT1 External Interrupt Priority bit
1 = High priority
0 = Low priority
Unimplmented: Read as ’0’
INT2IE: INT2 External Interrupt Enable bit
1 = Enables the INT2 external interrupt
0 = Disables the INT2 external interrupt
INT1IE: INT1 External Interrupt Enable bit
1 = Enables the INT1 external interrupt
0 = Disables the INT1 external interrupt
Unimplmented: Read as ’0’
INT2IF: INT2 External Interrupt Flag bit
1 = The INT2 external interrupt occurred (must be cleared in software)
0 = The INT2 external interrupt did not occur
INT1IF: INT1 External Interrupt Flag bit
1 = The INT1 external interrupt occurred (must be cleared in software)
0 = The INT1 external interrupt did not occur
Legend:
R = Readable bit
- n = Value at POR
Note:
INT2IP
R/W-1
Interrupt flag bits are set when an interrupt condition occurs, regardless of the state
of its corresponding enable bit, or the global enable bit. User software should ensure
the appropriate interrupt flag bits are clear prior to enabling an interrupt. This feature
allows software polling.
