5.15.5 PORT L INTERRUPTS
Port L provides the user with an additional eight fully selectable, edge sensitive interrupts which are all
vectored into the same service subroutine.
The interrupt from Port L shares logic with the wake-up circuitry. The register WKEN allows interrupts from
Port L to be individually enabled or disabled. The register WKEDG specifies the trigger condition to be
either a positive or a negative edge. Finally, the register WKPND latches in the pending trigger conditions.
The GIE (Global Interrupt Enable) bit enables the interrupt function.
A control flag, LPEN, functions as a global interrupt enable for Port L interrupts. Setting the LPEN flag will
enable interrupts and vice versa. A separate global pending flag is not needed since the register WKPND
is adequate.
Since Port L is also used for waking the device out of the HALT or IDLE modes, the user can elect to exit
the HALT or IDLE modes either with or without the interrupt enabled. If he elects to disable the interrupt,
then the device will restart execution from the instruction immediately following the instruction that placed
the microcontroller in the HALT or IDLE modes. In the other case, the device will first execute the interrupt
service routine and then revert to normal operation. (See HALT MODE for clock option wake-up
information.)
5.15.6 INTERRUPT SUMMARY
The device uses the following types of interrupts, listed below in order of priority:
1. The Software Trap non-maskable interrupt, triggered by the INTR (00 opcode) instruction. The
Software Trap is acknowledged immediately. This interrupt service routine can be interrupted only by
another Software Trap. The Software Trap should end with two RPND instructions followed by a re-
start procedure.
2. Maskable interrupts, triggered by an on-chip peripheral block or an external device connected to the
device. Under ordinary conditions, a maskable interrupt will not interrupt any other interrupt routine in
progress. A maskable interrupt routine in progress can be interrupted by the non-maskable interrupt
request. A maskable interrupt routine should end with an RETI instruction or, prior to restoring context,
