+CFG-PM-OPERATEMODE E1 (0 | 1 | 2) -> 1 (PSMOO), because sporadic position updates are required instead of continous tracking <10s
+(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-ACQPERIOD U4 -> 0ms, 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
