GetVectExtern2000

unsigned GetVectExtern2000( void );

Description

Reads the address of external interrupt table entry. This function really just returns what is present in the table. The return value is meaningless if the address of the external interrupt has not been written.

This function should be used for Rabbit 2000 processors that are marked IQ2T in the 3rd line of text across the face of the chip. It will work for other versions of the Rabbit 2000 but should be deprecated in favor of GetVectExtern3000() which allows the use of two external interrupts. (Please see document TN301, "Rabbit 2000 Microprocessor Interrupt Issue," on the Rabbit Semiconductor website for more information.)

Return value

Jump address in vector table.

Library
