PLL: PLL x4 and x8 Multiplier Ratios

Revision(s) Affected

0 and A

Details

When the PLL multiplier is set to x4 or x8 (by writing 0004 or 0008, respectively, in the PLLCR register), the watchdog is re-enabled and resets the device upon a WD overflow. With noisy board conditions, this problem may be observed with other PLL multipliers as well.

Workaround(s)

Do not use these multiplier values for these revisions.

This is fixed in the next revision of the silicon.
