Interrupt-request masking is performed individually per interrupt target by comparing the				DRAF
priority level assigned to a specific interrupt request with a target-specific priorityDRAFT DRAFT
threshold. The priority levels are defined as follows:	DRAFT DRAFT
• Priority level 0 corresponds to ‘masked’ (i.e. interrupt requests with priority 0 never					D
lead to an interrupt)		DRAFT
• Priority 1 corresponds to the lowest priority				DRA
• Priority 15 corresponds to the highest priority

Software interrupt support is provided and can be supplied for:

•Testing RTOS interrupt handling without using device-specific interrupt service routines

•Software emulation of an interrupt-requesting device, including interrupts

8.9.3VIC pin description

The VIC module in the LPC2917/19 has no external pins.

8.9.4VIC clock description

The VIC is clocked by CLK_SYS_VIC, see Section 7.2.2.
