beside reset pin , what may cause STR711FR2H6 reset?

application in GPS,

there was a time that when GPS module turned on consumes too much power can pull low the reset pin,but after this problem fixed,

the random reset still happens sometimes after the set running for a while.

also note that watchdog disabled!

A supply voltage drop on the V18 or V18Bkp below the threshold 1.35V (+/- 10%) causes a reset beside the reset pin, the watchdog and the software reset. You may check the power supply stage on the board :o

An erroneous jump to address zero could have the same effect as a proper reset in some applications.
