9.4.1
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, but retains its value in a manual reset and in
standby mode.
FRQCR:
Bits 15, 5, and 4—Frequency Multiplication Ratio (STC): These bits specify the frequency
multiplication ratio of PLL circuit 1.
