2.2.4.6
Figure 27 shows the MONITOR interrupt structure of the SCOUT-DX. The MONITOR
Data 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 inactive (0) 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.)
