Description
Internal Clock Frequency Division Ratio
These bits specify the frequency division ratio of the
internal clock with respect to the output frequency of
PLL circuit 1.
000: × 1 time
001: × 1/2 time
010: × 1/3 time
011: × 1/4 time
100: × 1/6 time
101: × 1/8 time
Output Range Select for PLL Circuit 1
When the multiplication ratio for the PLL circuit 1 is
specified to × 3, set this bit according to the output
frequency of the PLL circuit 1.
0: Low frequency mode
1: High frequency mode
Peripheral Clock Frequency Division Ratio
These bits specify the frequency division ratio of the
peripheral clock with respect to the output frequency
of PLL circuit 1.
000: × 1 time
001: × 1/2 time
010: × 1/3 time
011: × 1/4 time
100: × 1/6 time
101: × 1/8 time
110: × 1/12 time
(Output frequency of the PLL circuit 1 is equal to
or smaller than 120 MHz.)
(Multiplication ratio for the PLL circuit 1 is specified
to × 3 and its output frequency exceeds 120 MHz.)
