PC16550DN/NOPB Frequently Asked Questions (FAQs)

• What is the maximum baud rate supported by the PC16550DN?
  The PC16550DN supports baud rates up to 1.5 Mbps.
• How do I configure the PC16550DN for 9-bit data transmission?
  To configure the PC16550DN for 9-bit data transmission, set the MCR (Modem Control Register) to enable 9-bit mode, and set the LCR (Line Control Register) to select the 9-bit data length.
• What is the purpose of the FIFO (First-In-First-Out) buffer in the PC16550DN?
  The FIFO buffer in the PC16550DN is used to store received data temporarily, allowing the processor to handle other tasks while the UART handles the data reception.
• How do I handle flow control using the PC16550DN?
  The PC16550DN supports hardware flow control using RTS (Request to Send) and CTS (Clear to Send) signals. The RTS signal is used to request permission to send data, and the CTS signal is used to indicate when the receiver is ready to receive data.
• What is the power consumption of the PC16550DN?
  The PC16550DN has a typical power consumption of 30 mA at 5V and 15 mA at 3.3V, making it suitable for battery-powered applications.
