28.14.11 PMC Master Clock Register
Name:
Address:
Access:
• CSS: Master Clock Source Selection
• PRES: Processor Clock Prescaler
• UPLLDIV: UPLL Divider
0: UPLLDIV = 1 (clock is not divided).
1: UPLLDIV = 2 (clock is divided by 2).
UPLLDIV must be set (clock divided by 2) when UPLL is selected as source of clock for MCK.
