the XPWM timers. The maximum values assume that the XPWM output signal changes with

every cycle of the respective timer. In a real application the maximum XPWM frequency will

depend on the required resolution of the XPWM output signal (see Figure 18).

The Pulse Width Modulation Module consists of 4 independent PWM channels. Each

channel has a 16-bit up/down counter XPTx, a 16-bit period register XPPx with a shadow

latch, a 16-bit pulse width register XPWx with a shadow latch, two comparators, and the

necessary control logic. The operation of all four channels is controlled by two common

control registers, XPWMCON0 and XPWMCON1, and the interrupt control and status is

handled by one interrupt control register XP2IC, which is also common for all channels (see

Figure 11.2.1).
