Description
Multiplication factor setting
Specifies multiplication factor of the PLL circuit built
in the evaluation chip. The specified multiplication
factor becomes valid software standby mode, watch
mode, or subactive mode is entered.
These bits should be set to 11 in this LSI. Since the
value becomes STC1 = STC0 = 0 after a reset, set
STC1 = STC0 = 1.
00: × 1
01: × 2 (setting prohibited)
10: × 4 (setting prohibited)
11: PLL is bypass
