PLL Code A quick peek at the data sheet shows that this device implements 4 registers.
You clock in a 19 bit register value MSB first, followed by a two bit register selector.

Cannot set Watchdog timer prescaler You must first set the Watchdog Change Enable bit in WDTCR.
That bit will automatically clear in 4 clock cycles.
You must make your changes while it is still set.
