1.5.
The C8051F31x Family includes an SMBus/I2C interface, a full-duplex UART with enhanced baud rate
configuration, and an Enhanced SPI interface. Each of the serial buses is fully implemented in hardware
and makes extensive use of the CIP-51's interrupts, thus requiring very little CPU intervention.
1.6.
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 five 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. The external clock source selection is useful for real-time
clock functionality, where the PCA is clocked by an external source while the internal oscillator drives the
system clock.
Each capture/compare module can be configured to operate in one of six modes: Edge-Triggered Capture,
Software Timer, High Speed Output, 8- or 16-bit Pulse Width Modulator, or Frequency Output. Additionally,
Capture/Compare Module 4 offers watchdog timer (WDT) capabilities. Following a system reset, Module 4
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.
