The Programmable Counter Array (PCA0) provides enhanced timer functionality while requiring less CPU interven-
tion than the standard 8051 counter/timers. PCA0 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

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 independently in one of six modes: Edge-Triggered Capture, Software Timer, High-Speed Out-
put, Frequency Output, 8-Bit PWM, or 16-Bit PWM (each is described in
controlled through the system controller's Special Function Registers. The basic PCA block diagram is shown in
Figure 23.1.
