24. Programmable Counter Array
The Programmable Counter Array (PCA0) provides enhanced timer functionality while requiring less CPU
intervention than the standard 8051 counter/timers. PCA0 consists of a dedicated 16-bit counter/timer and
six 16-bit capture/compare modules. Each capture/compare module has its own associated I/O line
(CEXn) which is routed through the Crossbar to Port I/O when enabled (See
through 3 and the Priority Crossbar Decoder” on page
mable timebase that can select between six inputs as its source: 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 ECI line. Each capture/compare module may be configured to operate inde-
pendently in one of six modes: Edge-Triggered Capture, Software Timer, High-Speed Output, Frequency
Output, 8-Bit PWM, or 16-Bit PWM (each is described in
trolled through the system controller's Special Function Registers. The basic PCA block diagram is shown
in Figure 24.1.
