bit 7
INT2IP: INT2 External Interrupt Priority bit
1
= High priority
0
= Low priority
bit 6
INT1IP: INT1 External Interrupt Priority bit
1
= High priority
0
= Low priority
bit 5
Unimplemented: Read as ‘0’
bit 4
INT2IE: INT2 External Interrupt Enable bit
1
= Enables the INT2 external interrupt
0
= Disables the INT2 external interrupt
bit 3
INT1IE: INT1 External Interrupt Enable bit
1
= Enables the INT1 external interrupt
0
= Disables the INT1 external interrupt
bit 2
Unimplemented: Read as ‘0’
bit 1
INT2IF: INT2 External Interrupt Flag bit
1
= The INT2 external interrupt occurred (must be cleared by software)
0
= The INT2 external interrupt did not occur
bit 0
INT1IF: INT1 External Interrupt Flag bit
1
= The INT1 external interrupt occurred (must be cleared by software)
0
= The INT1 external interrupt did not occur
Note:
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 for software polling.
