Unimplemented: Read as ‘0’
USBDIV: USB Clock Selection bit (used in Full-Speed USB mode only; UCFG:FSEN = 1)
1 = USB clock source comes from the 96 MHz PLL divided by 2
0 = USB clock source comes directly from the primary oscillator block with no postscale
CPUDIV1:CPUDIV0: System Clock Postscaler Selection bits
For XT, HS, EC and ECIO Oscillator modes:
11 = Primary oscillator divided by 4 to derive system clock
10 = Primary oscillator divided by 3 to derive system clock
01 = Primary oscillator divided by 2 to derive system clock
00 = Primary oscillator used directly for system clock (no postscaler)
For XTPLL, HSPLL, ECPLL and ECPIO Oscillator modes:
11 = 96 MHz PLL divided by 6 to derive system clock
10 = 96 MHz PLL divided by 4 to derive system clock
01 = 96 MHz PLL divided by 3 to derive system clock
00 = 96 MHz PLL divided by 2 to derive system clock
PLLDIV2:PLLDIV0: PLL Prescaler Selection bits
111 = Divide by 12 (48 MHz oscillator input)
110 = Divide by 10 (40 MHz oscillator input)
101 = Divide by 6 (24 MHz oscillator input)
100 = Divide by 5 (20 MHz oscillator input)
011 = Divide by 4 (16 MHz oscillator input)
010 = Divide by 3 (12 MHz oscillator input)
001 = Divide by 2 (8 MHz oscillator input)
000 = No prescale (4 MHz oscillator input drives PLL directly)
