How to deassert WDOG-output-signal of iMX25

According to iMX25 Reference Manual,WDOG-output-signal is deasserted after POR-input-signal is asserted.

(Refer to Figure 48-10 "WDOG Time-Out Condition/WDT Bit Is Set") I want to deassert WDOG-output-signal after the watchdog-timeout occurs.

To do so,iMX25 needs POR-input-signal.

But I want to keep all Powers for iMX25 ON.(Don't want to power off all Powers) Can I assert POR-input-signal as all Powers ON. (without doing Power-OFF and Power-ON) And Can I connect WDOG-output-signal to POR-input-signal to deassert WDOG.
