Multipurpose Clock Generator (MCGV3)
16-22
b) Loop until CLKST (bits 3 and 2) in MCGSC are %11, indicating that the PLL output is selected
to feed MCGOUT in the current clock mode
– Now, With an RDIV of divide-by-8, a BDIV of divide-by-1, and a VDIV of multiply-by-32,
MCGOUT = [(8 MHz / 8) * 32] / 1 = 32 MHz, and the bus frequency is MCGOUT / 2, or
16 MHz
