| Description | Ch 7 Interrupt Trigger (sender). Default PL 0. |
|---|
The PL0 target reads this register along with its mask register to determine which initiator(s) caused the IPI interrupt. READ: 0: inactive. 1: active. WRITE: 0: no effect. 1: clears this bit. Note: If a Status bit is 1 and its Mask is 0, then the interrupt signal is asserted to the target interrupt controller. Note: These bit values can be read by the initiator using the initiators Observation register. Beware that this does not provide the initiator with the state of the target's Mask register.
