Bit 3

RFCUT

Description

System clock oscillator’s on-chip feedback resistor and duty adjustment

circuit are used

(Initial value)

System clock oscillator’s on-chip feedback resistor and duty adjustment circuit are not

used

Bit 2—Reserved: This bit can be read or written to, but should only be written with 0.

Bits 1 and 0—Frequency Multiplication Factor (STC1, STC0): The STC bits specify the

frequency multiplication factor of the PLL circuit incorporated into the evaluation chip. The

specified frequency multiplication factor is valid after a transition to software standby mode.

With the LSI, STC1 and STC0 must both be set to 1. After a reset, STC1 and STC0 are both

cleared to 0, and so must be set to 1.
