WAKEUP_IN Signal
The DTE controls the sleep and wakeup status of the MC509 module through the
WAKEUP_IN signal.
If there is no external WAKEUP_IN signal, the wireless module keeps in the wakeup
status by default. After receiving the WAKEUP_IN signal, the wireless module
determines whether to enter the sleep mode according to the level status of the
WAKEUP_IN signal.
Table 3-3 shows the definition of the WAKEUP_IN signal.

WAKEUP_OUT Signal
