TPS65381 to MCU Sync / SPNA176

Hello,

we are about to use a TPS65381 (SPI Mode) with an RM48 MCU.

In the SPNA176 PDF for theTPS65381  at

"3 Software Flowchart / 6. Synchronize the MCU Watchdog triggers on the Watchdog timer"

it says to wait for the TPS65381 watchdog timeout before periodically serving the watchdog.

The example source code is like this:

while (ecmpIfGetBit(ECMP_WDG_STATUS, 2) == 1);

If I am correct, this checks for bit 2 (D2) in the WDT_STATUS Register witch is the  SEQ_ERR flag.

Is this sufficient for sync or should the TIME_OUT flag ( bit 1 / D1) be checked (as alternative or additionally) like this ?:

while (ecmpIfGetBit(ECMP_WDG_STATUS, 1) == 1);

Thanks and Regards
