10 SpaceWire Plug-and-Play error (PE) - Generate an interrupt when a SpaceWire Plug and Play error has been
detected in the configuration port. The different errors are described in 13.5.4.
9 Spill-if-not-ready (SR) - Generate an interrupt when a packet has been spilled because of the spill-if-not-ready
feature described in section 13.2.10.
8 Run-state entry (RS) - Generate an interrupt when a SpaceWire link enters run-state.
7 Time code / distributed interrupt code tick truncation (TT) - Generate an interrupt when a packet has been spilled
because of the time code / distributed interrupt code truncation feature described in section 13.2.21.1.
6 Packet length truncation (PL) - Generate an interrupt when a packet has been spilled due to the packet length
truncation feature described in section 13.2.16.
5 Timeout spill (TS) - Generate an interrupt when a packet has been spilled due to the timeout mechanism.
4 Auxiliary configuration port error (AC) - Generate an interrupt when either a header CRC error, protocol ID
error, packet type error, early EOP, or early EEP has been detected in the configuration port.
3 RMAP error (RE) - Generate an interrupt when an error has been detected in the configuration port for an
RMAP command such that the PSTS.EC field is set to a non-zero value.
2 Invalid address (IA)- Generate an interrupt when an invalid address error has occurred on a port. See
RTR.PSTS:IA bit and section 13.2.12 for a definition of invalid address.
1 Link error (LE) - Generate an interrupt when a link error has been detected on a SpaceWire port.
0 Memory error (ME) - Generate an interrupt when a memory error occur in any of the router’s on-chip memories.

19: 0 Port interrupt enable (IE) - Set a bit to 1 to enable interrupts to be generated for an error detected in the port with
the same number as the bit index. An interrupt is optionally signalled through a distributed interrupt code.

19: 0 Interrupt pending (IP) - When a bit is set to 1, the port with the same number as the bit index was the source of
an interrupt. A bit in this field will only be set to 1 for a generated interrupt if the port’s corresponding bit in
RTR.IPMASK is set, as well as the error types corresponding bit in RTR.IMASK, are set.
