Legend:

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘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 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.
