The Programmable Counter Array (PCA0) provides enhanced timer functionality while requiring less CPU
intervention than the standard 8051 counter/timers. The PCA consists of a dedicated 16-bit counter/timer
and three 16-bit capture/compare modules. The counter/timer is driven by a programmable timebase that
can select between six sources: system clock, system clock divided by four, system clock divided by
twelve, the external oscillator clock source divided by 8, Timer 0 overflow, or an external clock signal on the
External Clock nput (ECI) input pin.
Each capture/compare module may be configured to operate independently in one of six modes: Edge-
Triggered Capture, Software Timer, High-Speed Output, Frequency Output, 8-Bit PWM, or 16-Bit PWM.
Additionally, PCA Module 2 may be used as a watchdog timer (WDT), and is enabled in this mode follow-
ing a system reset. The PCA Capture/Compare Module I/O and the External Clock Input may be routed to
Port I/O using the digital crossbar.
