6.16.2 Clock description
Interrupt-request masking is performed individually per interrupt target by comparing the
priority level assigned to a specific interrupt request with a target-specific priority
threshold. The priority levels are defined as follows:
Software interrupt support is provided and can be supplied for:
The VIC is clocked by CLK_SYS_VIC, see

•
Priority level 0 corresponds to ‘masked’ (i.e. interrupt requests with priority 0 never
lead to an interrupt).
Priority 1 corresponds to the lowest priority.
Priority 15 corresponds to the highest priority.
Testing RTOS (Real-Time Operating System) interrupt handling without using
device-specific interrupt service routines.
Software emulation of an interrupt-requesting device, including interrupts.
