TL16C550DPFBR Frequently Asked Questions (FAQs)

  • The maximum operating frequency of the TL16C550DPFBR is 16.5 MHz, but it can be overclocked up to 30 MHz with some limitations.
  • The FIFO buffers in the TL16C550DPFBR are 16 bytes deep and can be accessed through the THR (Transmit Holding Register) and RBR (Receive Buffer Register) registers. It's recommended to use the FIFO status flags to manage the buffer levels and avoid overflow or underflow conditions.
  • The XOFF (Transmit Off) and XON (Transmit On) characters are used for flow control in the TL16C550DPFBR. When the receiver's buffer is full, it sends an XOFF character to the transmitter to pause transmission. When the buffer has space available, it sends an XON character to resume transmission.
  • The baud rate of the TL16C550DPFBR is configured through the DLL (Divisor Latch Low Byte) and DLH (Divisor Latch High Byte) registers. The formula to calculate the baud rate is: Baud Rate = (Clock Frequency / (16 * (DLL + (DLH * 256))))
  • The main difference between the TL16C550DPFBR and the TL16C554DPFBR is that the TL16C554DPFBR has four independent UART channels, while the TL16C550DPFBR has only one UART channel.
