XDOV ... Transmit Data Overflow
More than 32 bytes have been written in one pool of the XFIFOD, i.e. data has been
overwritten.
XFW ... Transmit FIFO Write Enable
Data can be written in the XFIFOD. This bit may be polled instead of (or in addition to)
using the XPR interrupt.
XRNR ... Transmit RNR. Used in auto mode only
In auto mode, this bit indicates whether the IPAC receiver is in the “ready” (0) or “not
ready” (1) state. When “not ready”, the IPAC sends an RNR S-frame autonomously to
the remote station when an I frame or an S frame is received.
RRNR ... Receive RNR. Used in auto mode only
In the auto mode, this bit indicates whether the IPAC has received an RR or an RNR
frame, this being an indication of the current state of the remote station: receiver ready
(0) or receiver not ready (1).
MBR ... Message Buffer Ready
This bit signifies that temporary storage is available in the RFIFOD to receive at least the
first 16 bytes of a new message.
MAC1 ... MONITOR Transmit Channel 1 Active (IOM-2 terminal mode only)
Data transmission is in progress in MONITOR channel 1.
MAC0 ... MONITOR Transmit Channel 0 Active
Data transmission is in progress in MONITOR channel 0.
