10.4.1
The frequency control register (FRQCR) is a 16-bit read/write register that 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.
Bits 15, 5 and 4—Frequency Multiplication Ratio (STC2, STC1, STC0): These bits specify the
frequency multiplication ratio of PLL circuit 1.
