49.2 Embedded Characteristics

  • Two-pin UART
    • Independent Receiver and Transmitter with a common programmable Baud Rate Generator
    • Baud Rate can be driven by processor-independent generic source clock
    • Even, odd, mark or space parity generation
    • Parity, framing and overrun error detection
    • Automatic echo, Local Loopback and Remote Loopback Channel modes
    • Digital filter on receive line
    • Interrupt generation
    • Support for two PDC channels with connection to receiver and transmitter
    • Comparison function on received character
    • Optical link modulator and demodulator for communication compliant with ANSI-C12.18 or IEC62056-21 Standards
    • Receiver time-out
  • Register Write Protection
  • Analog Comparator Controller (ACC)
    • Bypasses UART receiver when ACC is enabled
    • Gives direct access to analog comparator (AC) output
    • Detects edges on AC output
    • Generates interrupt on AC output changes
