Notes :
1. The PRC0 bit in the PRCR register is set to "1" (write enable) before rewriting CM1 register.
2. When setting the CM10 bit to "1" to set XOUT to "H", an internal feedback resistance is disabled.
XIN, XCIN and XCOUT are placed on high-impedance.
3. When setting the CM10 bit to "1", the MCD4 to MCD0 bits in the MCD register are set to "010002"
(divide-by-8 mode). When setting the CM20 bit to "1" (oscillation stop detect function enabled) or
the CM21 bit to "1" (ring oscillator selected), avoid setting the CM10 bit to "1".
4. CM17 bit is enabled only when the CM21 bit in the CM2 register is set to "0". Follow a procedure
shown Figure in 1.8.13 to set the CM17 bit to "1".
