Frequency Control Register (FRQCR)
The frequency control register (FRQCR) has control bits assigned for the following functions:
clock output/non-output from the CKIO pin during software standby mode, the frequency
multiplication ratio of PLL circuit 1, and the frequency division ratio of the CPU clock and the
peripheral clock (P
φ).
(8)
Standby Control Register
The standby control register has bits for controlling the power-down modes. See section 27,
Power-Down Modes, for more information.
