Receive interrupt status MDR has two enable bits, MONITOR Receive interrupt Enable
(MRE) and MR bit Control (MRC). The MONITOR channel End of Reception MER,
MONITOR channel Data Acknowledged MDA and MONITOR channel Data Abort MAB
interrupt status bits have a common enable bit MONITOR Interrupt Enable MIE.
MRE prevents the occurrence of MDR status, including when the first byte of a packet is
received. When MRE is active (1) but MRC is inactive, the MDR interrupt status is
generated only for the first byte of a receive packet. When both MRE and MRC are
active, MDR is always generated and all received MONITOR bytes - marked by a 1-to-0
transition in MX bit - are stored. (Additionally, an active MRC enables the control of the
MR handshake bit according to the MONITOR channel protocol.)

The Command/Indication channel carries real-time status information between the
ISAC-SX and another device connected to the IOM-2 interface.
1. One C/I channel (called C/I0) conveys the commands and indications between the
The C/I0 channel is accessed via register CIR0 (in receive direction, layer-1 to layer-2)
and register CIX0 (in transmit direction, layer-2 to layer-1). The C/I0 code is four bits
long. A listing and explanation of the layer-1 C/I codes can be found in
Data Sheet
layer-1 and the layer-2 parts of the ISAC-SX. It can be accessed by an external layer-
2 device e.g. to control the layer-1 activation/deactivation procedures. C/I0 channel
access may be arbitrated via the TIC bus access protocol. In this case the arbitration
is done in IOM-2 channel 2 (see
