Table 69. INTDSTn Interrupt Status Decode Registers (INTDSTn_DECODE) Field Descriptions

Bit	Field	Value Description
31-0	ISDRn	Interrupt sources that select a particular physical interrupt destination, are mapped to specific bits in
		the decode register. The interrupt sources are mapped to an interrupt decode register, only if the
		ICRR routes the interrupt source to the corresponding physical interrupt. The status decode bit is a
		logical "OR" of multiple interrupt sources that are mapped to the same bit.
