§3-4. VCO-C Mode
This is VCO control mode. In this mode, the oscillation frequency of the internal master clock (VCLK) can be
controlled by setting $D commands VP0 to VP7 and VPCTL0, 1. The VCLK oscillation frequency can be
expressed by the following equation.
n: VP0 to VP7 setting value
1: VPCTL0, 1 setting value
1 (256 – n)
VCLK =
32
The VCO1 oscillation frequency is determined by VCLK. The VCO1 frequency can be expressed by the following
equation.
• When DSPB = 0
49
VCO1 = VCLK ×
24
• When DSPB = 1
49
VCO1 = VCLK ×
