Legend: R = Read only, R/W = Read/Write; -n = value after reset

†Default values for the PLLDIV0, PLLDIV1, PLLDIV2, and PLLDIV3 bits are /1 (0 0000), /1 (0 0000), /2 (0 0001), and /2 (0 0001), respectively.

CAUTION:

D1, and D2 should never be disabled. D3 should only be disabled if ECLKIN is used.

D2, and D3)‡

BIT #	NAME			DESCRIPTION
31:16	Reserved	Reserved. Read-only, writes have no effect.

		Divider Dx Enable (where x denotes 0 through 3).
		0	–	Divider x Disabled. No clock output.
15	DxEN	1	–	Divider x Enabled (default).

			These divider-enable bits are device-specific and must be set to 1 to enable.
	14:5	Reserved	Reserved. Read-only, writes have no effect.

			/2, and /2, respectively].

			01111	=	/16	11111	=	/32

‡Note that SYSCLK2 must run at half the rate of SYSCLK1. Therefore, the divider ratio of D2 must be two times slower than D1. For example, if D1 is set to /2, then D2 must be set to /4.
