a) MCGC2 = 0x08 (%00001000)
– IREFS (bit 2) set to 1 to select the internal reference clock as the reference clock source
– RDIV (bits 5-3) remain unchanged because the reference divider does not affect the internal

– LP (bit 3) in MCGSC is 1
– RANGE, HGO, EREFS, ERCLKEN, and EREFSTEN bits are ignored when the IREFS bit
