Operational Description
MOS Interrupt Logic
In the case of IOM-2 non-terminal timing modes only one MONITOR channel is handled
and MOR1 and MOX1 are unused.
The interrupt logic is different for MONITOR channel 0 and channel 1:
• MONITOR channel 0
The MONITOR Data Receive MDR0 and the MONITOR channel End of Reception
MER0 interrupt status have two enable bits, MONITOR Receive interrupt Enable
(MRE0) and MR bit Control (MRC0).
The MONITOR channel Data Acknowledged MDA0 and MONITOR channel Data Abort
MAB0 interrupt status bits have a common enable bit MONITOR Interrupt Enable MIE0.
MRE0 prevents the occurrence of MDR0 status, including when the first byte of a packet
is received. When MRE0 is active (1) but MRC0 is inactive, the MDR0 interrupt status is
generated only for the first byte of a receive packet. When both MRE0 and MRC0 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 MRC0 enables the control of the
MR handshake bit according to the MONITOR channel protocol.)
• MONITOR channel 1
The MONITOR Data Receive interrupt status MDR1 has two enable bits, MONITOR
Receive interrupt Enable (MRE1) and MR bit Control (MRC1). The MONITOR channel
End of Reception MER1, MONITOR channel Data Acknowledged MDA1 and MONITOR
channel Data Abort MAB1 interrupt status bits have a common enable bit MONITOR
Interrupt Enable MIE1.
MRE1 prevents the occurrence of MDR1 status, including when the first byte of a packet
is received. When MRE1 is active (1) but MRC1 is inactive, the MDR1 interrupt status is
generated only for the first byte of a receive packet. When both MRE1 and MRC1 are
active, MDR1 is always generated and all received MONITOR bytes - marked by a 1-
to-0 transition in MX bit - are stored. (Additionally, an active MRC1 enables the control
of the MR handshake bit according to the MONITOR channel protocol.)
