ROON
R/W-0
For ROSEL (REFOCON<4>), the primary oscillator is available only when configured as the default via the
FOSC settings. This is regardless of whether the device is in Sleep mode.
ROON: Reference Oscillator Output Enable bit
1 = Reference oscillator output available on REFO pin
0 = Reference oscillator output disabled
Unimplemented: Read as ‘0’
ROSSLP: Reference Oscillator Output Stop in Sleep bit
1 = Reference oscillator continues to run in Sleep
0 = Reference oscillator is disabled in Sleep
ROSEL: Reference Oscillator Source Select bit
1 = Primary oscillator (EC or HS) used as the base clock
0 = System clock used as the base clock; base clock reflects any clock switching of the device
RODIV<3:0>: Reference Oscillator Divisor Select bits
1111 = Base clock value divided by 32,768
1110 = Base clock value divided by 16,384
1101 = Base clock value divided by 8,192
1100 = Base clock value divided by 4,096
1011 = Base clock value divided by 2,048
1010 = Base clock value divided by 1,024
1001 = Base clock value divided by 512
1000 = Base clock value divided by 256
0111 = Base clock value divided by 128
0110 = Base clock value divided by 64
0101 = Base clock value divided by 32
0100 = Base clock value divided by 16
0011 = Base clock value divided by 8
0010 = Base clock value divided by 4
0001 = Base clock value divided by 2
0000 = Base clock value
