3.3.4 Wake-up via RTS0
RTS0 can be used to wake up PLSx3 from SLEEP mode configured with AT^SPOW. Assertion
of RTS0 (i.e., toggle from inactive high to active low) serves as wake up event, thus allowing
an external application to almost immediately terminate power saving. After RTS0 assertion,
the CTS0 line signals module wake up, i.e., readiness of the AT command interface. It is there-
fore recommended to enable RTS/CTS flow control (default setting).
Figure 31 shows the described RTS0 wake up mechanism.
