10.4.1
The frequency control register (FRQCR) is a 16-bit readable/writable register used to specify the
frequency multiplication ratio of PLL circuit 1, and the frequency division ratio of the internal
clock and the peripheral clock.
Only word access can be used on the FRQCR register. FRQCR is initialized to H'0102 by a
power-on reset trigged by the RESETP pin, but retains its value in a manual reset and in standby
mode.
FRQCR:
Bits 15, 5, and 4—Frequency Multiplication Ratio (STC2, STC1, STC0): These bits specify
the frequency multiplication ratio of PLL circuit 1.
