LINK Core Interrupt Status Register 0
The value of each bit of this register indicates the status of a corresponding interrupt source. If these bits become
“1” when the associated bit of the LINKIntEnb0 Register is “1”, this register asserts the interrupt signal to the
CPU.
The CPU reads this register after receiving the interrupt signal to locate an interrupt source. By writing the read
value again, it clears these bits.
Bit7 Unknown Expected Channel
When a packet of ISO channel not set in the CHANNEL_AVAILABLE Register is detected, this bit becomes
“1”.
It is enabled when the WonIRM = “1” of IRM IDStat Register (the self node is IRM).
Bit6 DuplicateChannelDetected
When a packet of a same channel is detected in the ISO period of 1 cycle, this bit becomes “1”.
It is enabled when the WonIRM = “1” of IRM IDStat Register (the self node is IRM).
Bit5 ISO Arbitration Failed
When an ISO packet transmit request is received but a SubAction Gap is detected before it is transmitted, this
bit becomes “1”.
Bit4 ISO Arbitration Failed
When a Cycle_START packet is received but a SubAction Gap cannot be detected even after the
ISOCHRONOUS_CYCLE_TIME has passed, this bit becomes “1”.
Bit3 Cycle Timer Over Flow
When the CYCLE_TIMER overflows, this bit becomes “1”.
Bit2 Local Cycle Event Occurred
When an local cycle event occurs, this bit becomes “1”.
Bit1 Cycle Start Packet Lost
When the CYCLE_START_PACKET does not exist over two local cycle events, this bit becomes “1”.
Bit0 CycleStartPkt Arbitration Failed
When a CYCLE_START_PACKET cannot be transmitted before the SubActionGap after a local cycle event
occurs, this bit becomes “1”. This bit is enabled when cmstr = “1”.
