1.5.
The C8051F018/9 have an on-board Programmable Counter/Timer Array (PCA) in addition to the four 16-bit
general-purpose counter/timers.
programmable capture/compare modules. The timebase gets its clock from one of four sources: the system clock
divided by 12, the system clock divided by 4, Timer 0 overflow, or an External Clock Input (ECI).
Each capture/compare module can be configured to operate in one of four modes: Edge-Triggered Capture,
Software Timer, High Speed Output, or 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.
1.6.
The C8051F0018/9 include a Full-Duplex UART, SPI Bus, and I2C/SMBus. Each of the serial buses is fully
implemented in hardware and makes extensive use of the CIP-51’s interrupts, thus requiring very little intervention
by the CPU. The serial buses do not “share” resources such as timers, interrupts, or Port I/O, so any or all of the
serial buses may be used together.
