The fourmost significant bits are copied from the register
These bits are supplied by the CMFP. They are the binary channel number of the highest
priority channel that is requesting interrupt service.

Theupper fourbits of the vector register are written by the user. These bits become themost
significant four bits of the interrupt vector number.
In-Service Register Enable. When the Sbit is zero,the CMFP isin the automatic end-of-in-
terrupt mode and the In-Service register bits are forced low. When the S bit is a one, the
CMFP is in the software end-of-interrupt mode and the In-Service register bits areenabled.
Unused bits,read as zero.
