PLLODIV<2:0>: Output Divider for PLL
111 = PLL output divided by 256
110 = PLL output divided by 64
101 = PLL output divided by 32
100 = PLL output divided by 16
011 = PLL output divided by 8
010 = PLL output divided by 4
001 = PLL output divided by 2
000 = PLL output divided by 1
Note: On Reset these bits are set to the value of the FPLLODIV configuration bits
(DEVCFG2<18:16>)
FRCDIV<2:0>: Fast Internal RC Clock Divider bits
111 = FRC divided by 256
110 = FRC divided by 64
101 = FRC divided by 32
100 = FRC divided by 16
011 = FRC divided by 8
010 = FRC divided by 4
001 = FRC divided by 2 (default setting)
000 = FRC divided by 1
Reserved: Write ‘0’; ignore read
SOSCRDY: Secondary Oscillator Ready Indicator bit
1 = Indicates that the Secondary Oscillator is running and is stable
0 = Secondary oscillator is either turned off or is still warming up
Reserved: Write ‘0’; ignore read
