28. Programmable Counter Array
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 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. The counter/timer is driven by a
programmable timebase that can select between seven sources: system clock, system clock divided by
four, system clock divided by twelve, the external oscillator clock source divided by 8, SmaRTClock divided
by 8 ('F912 and 'F902 devices only), Timer 0 overflows, or an external clock signal on the 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 to 11-Bit PWM, or 16-Bit
PWM (each mode is described in Section “28.3. Capture/Compare Modules” on page 363). The external
oscillator clock option is ideal for real-time clock (RTC) functionality, allowing the PCA to be clocked by a
precision external oscillator while the internal oscillator drives the system clock. The PCA is configured and
controlled through the system controller's Special Function Registers. The PCA block diagram is shown in
Figure 28.1.
Important Note: The PCA Module 5 may be used as a watchdog timer (WDT), and is enabled in this mode
following a system reset. Access to certain PCA registers is restricted while WDT mode is enabled .
See Section 28.4 for details.
