ROON: Reference Oscillator Output Enable bit
1 = Reference oscillator output is enabled on REFCLK pin⁽²⁾
0 = Reference oscillator output is disabled
Unimplemented: Read as ‘0’
ROSSLP: Reference Oscillator Run in Sleep bit
1 = Reference oscillator output continues to run in Sleep
0 = Reference oscillator output is disabled in Sleep
ROSEL: Reference Oscillator Source Select bit
1 = Oscillator crystal used as the reference clock
0 = System clock used as the reference clock

1111 = Reference clock divided by 32,768
1110 = Reference clock divided by 16,384
1101 = Reference clock divided by 8,192
1100 = Reference clock divided by 4,096
1011 = Reference clock divided by 2,048
1010 = Reference clock divided by 1,024
1001 = Reference clock divided by 512
1000 = Reference clock divided by 256
0111 = Reference clock divided by 128
0110 = Reference clock divided by 64
0101 = Reference clock divided by 32
0100 = Reference clock divided by 16
0011 = Reference clock divided by 8
0010 = Reference clock divided by 4
0001 = Reference clock divided by 2
0000 = Reference clock
Unimplemented: Read as ‘0’
Note 1: The reference oscillator output must be disabled (ROON = 0) before writing to these bits.
2: This pin is remappable. See Section 11.4 “Peripheral Pin Select” for more information.
