SYNOPSYS
	interrupt = AddICRVector(iCRBit, interrupt), resource
	D0			 D0	 A1		A6


FUNCTION

Assign interrupt processing code to a particular interrupt bit of the 
CIA ACR. If the interrupt bit has already been assigned, this function
will fail, and return a pointer to the owner interrupt. If it succeeds
a NULL is returned.

This function will also enable the CIA interrupt for the given ICR bit.

INPUTS
	iCRBit - bit number to set (0..4)
	interrupt -- pointer to interrupt structure

RESULT
	interrupt -- zero if successful, otherwise returns a pointer
		to the current owner interrupt structure.

SEE ALSO
	RemICRvector

--------

SYNOPSYS
	RemICRVector(iCRBit, interrupt), resource
			D0	A1	  A6

FUNCTION
Disconnect interrupt processing code for a particular interrupt bit
of the CIA ICR.

This function will also disable the CIA interrupt for the given
ICR bit.

INPUTS
	iCRBit -- bit number to set (0..4)
	interrupt -- pointer to interrupt structure

Enjoy.
