FCS Error Interrupt Status
Indicates if the FCS Error Interrupt has occurred since the last read
of this register. Receive HDLC1 Controller will declare this interrupt
if it detects an error in the most recently received data message.

Receipt of Abort Sequence Interrupt Status
Indicates if the Receipt of Abort interrupt has occurred since last
read of this register. Receive HDLC1 Controller will declare this
interrupt if it detects a string of seven (7) consecutive 1’s in the
incoming data link channel.

Receipt of Idle Sequence Interrupt Status
Indicates if the Receipt of Idle Sequence interrupt has occurred
since the last read of this register. The Receive HDLC1 Controller
will declare this interrupt if it detects the flag sequence octet (0x7E)
in the incoming data link channel.
0 = Receipt of Idle Sequence interrupt has not occurred since last
