1.4.
An on-chip Programmable Counter/Timer Array (PCA) is included in addition to the four 16-bit general pur-
pose counter/timers. The PCA consists of a dedicated 16-bit counter/timer time base with six programma-
ble capture/compare modules. The PCA clock is derived from one of six sources: the system clock divided
by 12, the system clock divided by 4, Timer 0 overflows, an External Clock Input (ECI), the system clock, or
the external oscillator clock source divided by 8.
Each capture/compare module can be configured to operate in a variety of modes: edge-triggered capture,
software timer, high-speed output, pulse width modulator (8, 9, 10, 11, or 16-bit), or frequency output. Addi-
tionally, Capture/Compare Module 5 offers watchdog timer (WDT) capabilities. Following a system reset,
Module 5 is configured and enabled in WDT mode. The PCA Capture/Compare Module I/O and External
Clock Input may be routed to Port I/O via the Digital Crossbar.

C8051F93x-C8051F92x devices have a 300 ksps, 10-bit successive-approximation-register (SAR) ADC
with integrated track-and-hold and programmable window detector. ADC0 also has an autonomous low
power Burst Mode which can automatically enable ADC0, capture and accumulate samples, then place
ADC0 in a low power shutdown mode without CPU intervention. It also has a 16-bit accumulator that can
automatically average the ADC results, providing an effective 11, 12, or 13 bit ADC result without any addi-
tional CPU intervention.
