Abstract
A universal asynchronous receiver/transmitter (UART) module is disclosed. The UART module may include a receiver unit being clocked by a programmable receiver clock configured to sample an incoming data signal and comprising a counter clocked by said receiver clock, wherein the counter is reset to start counting with every falling edge of the data signal and to trigger a BRK detection signal if the counter reaches a programmable threshold value.
