Interrupt Multiplexer (INTMUX)
About this module
25.1.1 Introduction
The Interrupt Multiplexer (INTMUX) expands the number of peripherals that can
interrupt the core via 4 channels of the NVIC module.
• The INTMUX module has 4 channels that are assigned to 4 NVIC interrupt slots.
• Each INTMUX channel can provide up to 32 additional interrupt sources, which can
be logically OR'd or ANDed.
• The Interrupt Multiplexer (INTMUX) routes the interrupt sources to the interrupt
outputs.
25.1.2 Features
INTMUX features:
• Supports 4 multiplex channels
• Each channel receives 32 interrupt sources and has 1 interrupt output
• Each interrupt source can be enabled or disabled
• Each channel supports Logic AND or Logic OR of all enabled interrupt sources
