14.2 Zynq IP - What are the units used in the UART receiver timeout error interrupt status?

描述

On page 463 of the Zynq TRM (UG585) it states, "TIMEOUT: Receiver Timeout Error interrupt status. This event is triggered whenever the receiver timeout counter has expired due to a long idle condition".

However, what are the units of this timeout? Is this based on the baud_clock/bit_clock or the baud_sample?

解决方案

The receiver timeout counter is based on baud_clock/bit_clock and not on baud_sample. This is shown in the diagram below:
