SC16C554BIB80,557 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SC16C554BIB80,557?
  The maximum clock frequency for the SC16C554BIB80,557 is 16 MHz.
• How do I configure the UART for 9-bit data transmission?
  To configure the UART for 9-bit data transmission, set the MCR[7] bit to '1' and the LCR[0] bit to '1'. This enables 9-bit data transmission with an extra bit for parity or other uses.
• What is the purpose of the XOFF and XON characters in the SC16C554BIB80,557?
  The XOFF (Transmit Off) and XON (Transmit On) characters are used for software flow control. When the receiver sends an XOFF character, the transmitter stops sending data. When the receiver sends an XON character, the transmitter resumes sending data.
• How do I implement hardware flow control using the SC16C554BIB80,557?
  To implement hardware flow control, connect the RTS (Request to Send) output to the CTS (Clear to Send) input of the remote device. The SC16C554BIB80,557 will assert RTS when its transmit FIFO is full, and de-assert RTS when its transmit FIFO has space available.
• What is the maximum baud rate deviation tolerance for the SC16C554BIB80,557?
  The maximum baud rate deviation tolerance for the SC16C554BIB80,557 is ±4.5%.
