LPC2917/19
ARM9 microcontroller with CAN and LIN
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:
• 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
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
8.9.3 VIC pin description
The VIC module in the LPC2917/19 has no external pins.
8.9.4 VIC clock description
The VIC is clocked by CLK_SYS_VIC, see Section 7.2.2.
