8.19.7 Alternating output mode
In asymmetrical mode, the user can set up PWM channels A/B and C/D as alternating
pairs for bridge drive control. In this mode the output of these PWM channels are
alternately gated on every counter cycle.
8.19.8 PLL operation
The PWM module features a PLL that can be used to generate a CCUCLK frequency
between 16 MHz and 32 MHz. At this frequency the PWM module provides ultrasonic
PWM frequency with 10-bit resolution provided that the crystal frequency is 1 MHz or
higher. The PLL is fed an input signal from 0.5 MHz to 1 MHz and generates an output
signal of 32 times the input frequency. This signal is used to clock the timer. The user will
have to set a divider that scales PCLK by a factor from 1 to 16. This divider is found in the
SFR register TCR21. The PLL frequency can be expressed as shown in Equation 1.

Where: N is the value of PLLDV.3 to PLLDV.0.
Since N ranges from 0 to 15, the CCLK frequency can be in the range of PCLK to PCLK
16.
