8-bit microcontroller with accelerated two-clock 80C51 core
7.22.7 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.
7.22.8 PLL operation
The PWM module features a Phase Locked Loop 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:
