In UG367 for ADuCM360, there is reference to pin 46 (P2.0/SCL/UARTCLK) being an General-Purpose Input/Output P2.0/I2C Serial Clock Pin/Input Clock Pin for UART Block Only. What is meant by “UART Block only”?
This feature is not enabled, so Input Clock Pin for UART Block Only shouldn't have been documented
The purpose of it was to allow an external clock with a better accuracy than the system 16MHz oscillator to clock the UART block.
What is the background for your question? Do you need to your UART to have a tighther frequency accuracy? What for?
