LINK Core Interrupt Status Register 1
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 LINKIntEnb1 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 Reserved
Bit6 Reserved
Bit5 Reserved
Bit4 Reserved
Bit3 RxOnTardy
When a packet is received when the ChipCtl. SendTardy bit is “1”, an Ack_tardy is returned to the party of the
other end and this bit becomes “1”.
Bit2 Receive Packet Header CRC Error
When an error exists in the header CRC of a received packet, this bit becomes “1”.
Bit1 Receive Packet Tcode Unknown
When the Tcode in a received packet is invalid, this bit becomes “1”.
Bit0 transmit Retry Exceeded
If a transmit retry fails since the set value of the MaxRetry Register is exceeded when the RetryLimit Register
is not zero or the MaxRetry Register is not 0 and this bit becomes “1”.
