PIC32 PWRT

I was looking through Section 9: Watchdog Timer and Power-up Timer, and I quote ...
 
The PWRT, when enabled, holds the device in Reset for a 64 millisecond period after the normal Power-on Reset (POR) start-up period is complete. This allows additional time for the Primary Oscillator (POSC) clock source and the power supply to stabilize ...
 
However, I find no mechanism to enable PWRT in the datasheets, and no mention of any register that controls this feature for my PIC32MX150F128D. Does this mean that the feature is enabled automatically?

    From http://ww1.microchip.com/...eviceDoc/60001114G.pdf page 21

    9.6 I/O PINS
    The PWRT is disabled when the internal voltage regulator is enabled. A device without an
    internal voltage regulator will always have the PWRT enabled. A device with an internal voltage
    regulator will enable the PWRT when the VREG pin is tied to ground (to disable the regulator).
