The GP Timers provide a time base for the operation of the compare units, and associated PWM
circuits to generate PWM outputs. Additionally, they provide a time base for the operation of the
quadrature encoder pulse (QEP) circuit (GP Timer 2 for EVA, and GP Timer 4 for EVB only)
and the capture units. The GP Timers can also be used to generate a sampling period in a control
system.
