RTI Clock Select — RTIOSCSEL selects the clock source to the RTI. Either IRCCLK or OSCCLK. Changing the
RTIOSCSEL bit re-starts the RTI time-out period.
RTIOSCSEL can only be set to 1, if UPOSC=1.
UPOSC= 0 clears the RTIOSCSEL bit.
0 RTI clock source is IRCCLK.
1 RTI clock source is OSCCLK.
COP Clock Select 0 — COPOSCSEL0 and COPOSCSEL1 combined determine the clock source to the COP
(see also
If COPOSCSEL1 = 1, COPOSCSEL0 has no effect regarding clock select and changing the COPOSCSEL0 bit
does not re-start the COP time-out period.
When COPOSCSEL1=0,COPOSCSEL0 selects the clock source to the COP to be either IRCCLK or OSCCLK.
Changing the COPOSCSEL0 bit re-starts the COP time-out period.
COPOSCSEL0 can only be set to 1, if UPOSC=1.
UPOSC= 0 clears the COPOSCSEL0 bit.
0 COP clock source is IRCCLK.
1 COP clock source is OSCCLK
