† 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.<br />
CAUTION:<br />
D1 and D2 should never be disabled. D3 should only be disabled if ECLKIN is used.<br />
Table 41. PLL Wrapper Divider x Registers (Prescaler Divider D0 and Post-Scaler Dividers D1,<br />
D2, and D3) Description ‡<br />
BIT # NAME DESCRIPTION<br />
31:16 Reserved Reserved. Read-only, writes have no effect.<br />
15 DxEN<br />
Divider Dx Enable (where x denotes 0 through 3).<br />
0 – Divider x Disabled. No clock output.<br />
1 − Divider x Enabled (default).<br />
These divider-enable bits are device-specific and must be set to 1 to enable.<br />
14:5 Reserved Reserved. Read-only, writes have no effect.<br />
PLL Divider Ratio [Default values for the PLLDIV0, PLLDIV1, PLLDIV2, and PLLDIV3 bits are /1, /1,<br />
/2, and /2, respectively].<br />
4:0 PLLDIVx<br />
00000 = /1 10000 = /17<br />
00001 = /2 10001 = /18<br />
00010 = /3 10010 = /19<br />
00011 = /4 10011 = /20<br />
00100 = /5 10100 = /21<br />
00101 = /6 10101 = /22<br />
00110 = /7 10110 = /23<br />
00111 = /8 10111 = /24<br />
01000 = /9 11000 = /25<br />
01001 = /10 11001 = /26<br />
01010 = /11 11010 = /27<br />
01011 = /12 11011 = /28<br />
01100 = /13 11100 = /29<br />
01101 = /14 11101 = /30<br />
01110 = /15 11110 = /31<br />
01111 = /16 11111 = /32<br />
‡ 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,<br />
if D1 is set to /2, then D2 must be set to /4.<br />
