1.5.
The C8051F06x MCU family includes an on-board Programmable Counter/Timer Array (PCA) in addition
to the five 16-bit general purpose counter/timers. The PCA consists of a dedicated 16-bit counter/timer
time base with 6 programmable capture/compare modules. The timebase is clocked from one of six
sources: the system clock divided by 12, the system clock divided by 4, Timer 0 overflow, an External
Clock Input (ECI pin), the system clock, or the external oscillator source divided by 8.
Each capture/compare module can be configured to operate in one of six modes: Edge-Triggered Capture,
Software Timer, High Speed Output, Frequency Output, 8-Bit Pulse Width Modulator, or 16-Bit Pulse Width
Modulator. The PCA Capture/Compare Module I/O and External Clock Input are routed to the MCU Port I/
O via the Digital Crossbar.
