Legend:

R = Readable bit

-n = Value at POR

W = Writable bit

‘1’ = Bit is set

U = Unimplemented bit, read as ‘0’

‘0’ = Bit is cleared

x = Bit is unknown

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 in 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 in 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 interrupt enable bit. User software should ensure the appropriate interrupt flag bits

are clear prior to enabling an interrupt. This feature allows for software polling.
