Table 18:
Wake-up events in NON-CYCLIC and CYCLIC SLEEP modes
1)
During the CYCLIC SLEEP modes 5, 6, 7, and 8, RTS0 is conventionally
used for flow control: The assertion of RTS_0 signal that the application is
ready to receive data - without waking up the module. If the module is in
CFUN=0 mode the assertion of RTS0 serves as a wake-up event, giving the
application the possibility to intentionally terminate power saving. If the
module is in CFUN=9 mode, the assertion of RTS_0 can be used to
temporarily wake up I56/I56i for the time specified with the AT^SCFG
command (default = 2 s).
2)
Recommendation: In NON-CYCLIC SLEEP mode, you can set an RTC
alarm to wake up I56/I56i and return to full functionality. This is a useful
approach because, in this mode, the AT interface is not accessible.
