ROON:

Reference Oscillator Output Enable bit

= Reference oscillator output enabled on REFCLK0(2) pin

= Reference oscillator output disabled

bit 14

Unimplemented:

Read as ‘0’

bit 13

ROSIDL:

Reference Oscillator Run in Sleep bit

= Reference oscillator output continues to run in Sleep

= Reference oscillator output is disabled in Sleep

bit 12

ROSEL:

0000

= Reference clock

bit 7-0

Unimplemented:

Read as ‘0’

Note 1:

The reference oscillator output must be disabled (ROON = 0) before writing to these bits.

This pin is remappable. Refer to Section 10.4 “Peripheral Pin Select” for more information.
