Bit 12/Transmit FIFO Empty (TEMPTY).
This read-only real-time status bit will be set to a one when
the transmit FIFO is empty. It will be cleared when the transmit FIFO contains one or more bytes. This
status bit cannot cause a hardware interrupt.
Bit 13/Receive FIFO Overrun (ROVR).
This latched read-only event-status bit will be set to a one each
time the receive FIFO overruns. This bit will be cleared when read and will not be set again until another
overrun occurs (i.e., the FIFO has been read from and then allowed to fill up again). The setting of this bit
can cause a hardware interrupt to occur if the ROVR bit in the Interrupt Mask for HSR (IHSR) register is
set to a one and the HDLC bit in the Interrupt Mask for MSR (IMSR) register is set to a one. The
interrupt will be allowed to clear when this bit is read.
Bit 14/Receive FIFO Empty (REMPTY).
This real-time bit will be set to a one when the Receive FIFO
is empty and will be set to a zero when the Receive FIFO is not empty.
Bit 15/Receive Abort Sequence Detected (RABT).
This latched read-only event-status bit will be set to
a one each time the receive HDLC controller detects seven or more ones in a row during packet reception.
If the receive HDLC is not currently receiving a packet, then seven or more ones in a row will not trigger
this status bit. This bit will be cleared when read and will not be set again until another abort is detected
(at least one valid flag must be detected before another abort can be detected). The setting of this bit can
cause a hardware interrupt to occur if the RABT bit in the Interrupt Mask for HSR (IHSR) register is set
to a one and the HDLC bit in the Interrupt Mask for MSR (IMSR) register is set to a one. The interrupt
will be allowed to clear when this bit is read.
