SC16C752BIBS,151 datasheet by NXP Semiconductors

SC16C752BIBS,151 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SC16C752BIBS,151?
  The maximum operating frequency of the SC16C752BIBS,151 is 5 MHz.
• How do I configure the UART for 9-bit data transmission?
  To configure the UART for 9-bit data transmission, set the MCR register to enable 9-bit mode, and then set the LCR to select the 9-bit character length.
• What is the purpose of the RTS and CTS signals in the SC16C752BIBS,151?
  The RTS (Request to Send) and CTS (Clear to Send) signals are used for flow control in the UART. RTS is an output signal that indicates the transmitter is ready to send data, and CTS is an input signal that indicates the receiver is ready to receive data.
• How do I handle FIFO overflow and underflow in the SC16C752BIBS,151?
  To handle FIFO overflow and underflow, implement a FIFO management mechanism in your firmware to monitor the FIFO levels and adjust the data transmission rate accordingly. You can also use the UART's built-in FIFO threshold interrupts to trigger actions when the FIFO reaches certain levels.
• What is the recommended power-on reset (POR) circuit for the SC16C752BIBS,151?
  The recommended POR circuit for the SC16C752BIBS,151 involves connecting a 10 kΩ resistor and a 10 μF capacitor between the VCC and GND pins to ensure a clean power-on reset signal.
