SC16C750BIB64,157 Frequently Asked Questions (FAQs)

• What is the maximum clock frequency for the SC16C750BIB64,157?
  The maximum clock frequency for the SC16C750BIB64,157 is 40 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[2] bit to '1'. This enables 9-bit data transmission with a 9th bit as a parity bit.
• What is the purpose of the XOFF and XON characters in the SC16C750BIB64,157?
  The XOFF (Transmit Off) and XON (Transmit On) characters are used for software flow control. 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.
• How do I implement RTS/CTS flow control with the SC16C750BIB64,157?
  To implement RTS/CTS flow control, connect the RTS (Request to Send) output to the CTS (Clear to Send) input of the remote device. The SC16C750BIB64,157 will assert RTS when its transmit buffer is full, and de-assert RTS when the buffer has space available. The remote device will then assert CTS to allow transmission or de-assert CTS to pause transmission.
• What is the maximum baud rate deviation tolerance for the SC16C750BIB64,157?
  The maximum baud rate deviation tolerance for the SC16C750BIB64,157 is ±4.5%.
