Unimplemented: Read as ‘0’
111111111111111 = Output clock is source clock frequency divided by 65,534

000000000000010 = Output clock is source clock frequency divided by 4
000000000000001 = Output clock is source clock frequency divided by 2
000000000000000 = Output clock is same frequency as source clock (no divider)
ON: Output Enable bit
1 = Reference Oscillator Module enabled
0 = Reference Oscillator Module disabled
Unimplemented: Read as ‘0’
SIDL: Peripheral Stop in Idle Mode bit
1 = Discontinue module operation when device enters Idle mode
0 = Continue module operation in Idle mode
OE: Reference Clock Output Enable bit
1 = Reference clock is driven out on REFCLKO pin
0 = Reference clock is not driven out on REFCLKO pin
RSLP: Reference Oscillator Module Run in Sleep bit
1 = Reference Oscillator Module output continues to run in Sleep
0 = Reference Oscillator Module output is disabled in Sleep
Unimplemented: Read as ‘0’
DIVSWEN: Divider Switch Enable bit
1 = Divider switch is in progress
0 = Divider switch is complete
ACTIVE: Reference Clock Request Status bit
1 = Reference clock request is active
0 = Reference clock request is not active

The ROSEL and RODIV bits should not be written while the ACTIVE bit is ‘1’, as undefined behavior may
result.
This bit is ignored when the ROSEL<3:0> bits = 0000 or 0001.
While the ON bit is set to ‘1’, writes to these bits do not take effect until the DIVSWEN bit is also set to’1’.
