External maskable interrupts
This microcontroller provides maskable external interrupts INTPn with the
following features:
• Analog input filter (refer to
“Analog filtered inputs“ on page 102
)
• Interrupt detection selectable for each interrupt input:
– Rising edge
– Falling edge
– Both edges: rising and falling edge
– High level
– Low level
• Wakeup capability from stand-by mode of INTPn upon
– Rising edge
– Falling edge
– Both edges: rising and falling edge
For configuration of the external interrupt events refer to
“Edge and Level
Detection Configuration“ on page 218
.
5.3.9
Software interrupts
This microcontroller provides maskable software interrupts to for processing of
an interrupt service routine by the application software.
For initiating a software interrupt the interrupt request flag xxIC.xxIF of the
concerned software interrupt “xx” must be set to 1. The following processing is
identical to that of all other maskable interrupts.
