Product data sheet
6.17 Vectored interrupt controller
Table 32.
Legend:
‘1’ Indicates that the related register bit is tied off to logic HIGH, all writes are ignored
‘0’ Indicates that the related register bit is tied off to logic LOW, all writes are ignored
‘+’ Indicates that the related register bit is readable and writable
The LPC2939 contains a very flexible and powerful Vectored Interrupt Controller (VIC) to
interrupt the ARM processor on request.
The key features are:
