pins
Note:

10.6.3 Advantages

This solution enables handshake between UART and WAKEUP_OUT.
With software configuration, the host can go to sleep with no data loss.

10.7 System with Other Connection Methods

If the host can be connected to the module only using UART, refer to the
MU609 HSPA LGA Module Hardware
Issue 02 (2013-09-18)
If the host connects to the module using the TXD or RXD pin only, handshake is not
implemented and consequently data on the UART may be lost when the host is in sleep mode.
