SC16C752BIB48,157 datasheet by NXP Semiconductors

SC16C752BIB48,157 Frequently Asked Questions (FAQs)

• What is the maximum operating frequency of the SC16C752BIB48,157?
  The maximum operating frequency of the SC16C752BIB48,157 is 16.384 MHz.
• How do I configure the UART for 9-bit data transmission?
  To configure the UART for 9-bit data transmission, set the MCR[7:5] bits to '011' and the LCR[2] bit to '1'. This enables 9-bit data transmission with an additional parity bit.
• What is the purpose of the nINT signal?
  The nINT signal is an interrupt output that is asserted when a receive interrupt occurs, such as when a character is received or a transmitter holding register is empty.
• Can I use the SC16C752BIB48,157 in a 3.3V system?
  Yes, the SC16C752BIB48,157 is compatible with 3.3V systems. However, ensure that the input voltage (VCC) is within the recommended operating range of 3.0V to 3.6V.
• How do I reset the UART?
  To reset the UART, assert the nRESET signal low for at least 10 clock cycles. This resets the UART to its default state.
