20. PROGRAMMABLE COUNTER ARRAY
The Programmable Counter Array (PCA) 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 five
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 Section 15.1 for details on configuring the Crossbar).
The counter/timer is driven by a configurable timebase that can select between four inputs as its source: system
clock divided by twelve, system clock divided by four, Timer 0 overflow, or an external clock signal on the ECI
line. The PCA is configured and controlled through the system controller’s Special Function Registers. The basic
PCA block diagram is shown in Figure 20.1.
