Abstract
A data processing system ( ) has a multifield register ( ) which has two fields, a selection field ( ) and an information field ( ). The selection field ( ) identifies the source of the information loaded in the information field ( ). In one embodiment, the multifield register ( ) is an interrupt flag register ( ) and the selection field ( ) identifies which of the two registers portions ( ) of the interrupt pending register ( ) is loaded into the multifield register ( ). The low register portion ( ) can identify up to thirty-one sources of interrupt requests and the high register portion ( ) can identify up to thirty-two sources of interrupt requests even though the information field ( ) is only thirty-one bits. This is achievable because the selection field ( ) may serves a dual function, namely as a flag bit and as bit- of the interrupt pending register ( ).
