M-BUS SERIAL INTERFACE
8
The software supported M-Bus interrupt related control and status bits are at the following
registers:
SIFC - Software M-Bus Interrupt Flag Clear
1 (set)
Clear software supported M-Bus interrupt ag in MSR.
0 (clear) –
No effect.
SIIC - Software M-Bus Enable
1 (set)
If PC6 and PC7 satises the “Start” condition of the M-Bus protocol,
SIF in the MSR will be set and M-Bus interrupt will be generated.
0 (clear) –
PC6 and PC7 pins are congured for standard I/O operation.
SIF - Software Supported M-Bus Interrupt Flag
1 (set)
Software M-Bus interrupt has occurred.
0 (clear) –
No software M-Bus interrupt has occurred.
