-(PSMCT) CFG-PM-POSUPDATEPERIOD U4 -> 0ms, no self-timed wakup because receiver power mode is controlled via "software standby

-mode" by legacy UBX-RXM-PMREQ request CFG-PM-ONTIME U4 -> 0ms, optional I guess CFG-PM-EXTINTBACKUP L -> 1, force receiver into
-BACKUP mode when EXTINT (should be connected to GPS_EN_PIN) pin is "low"
-
-This is required because the receiver never enters low power mode if microcontroller is in deep-sleep.
-Maybe the changing UART_RX levels trigger a wakeup but even with UBX-RXM-PMREQ[12] = 0x00 (all external wakeup sources disabled)
-the receivcer remains in aquisition state -> potentially a bug
-
-Workaround: Control the EXTINT pin by the GPS_EN_PIN signal
-
-As mentioned in the M10 operational issues down below, power save won't allow the use of BDS B1C.
