Does serial_clear() disable the FIFO?

[adamgreen]

As I was code reviewing the serial_api.c source code for the LPC176X port, I noticed the following code in serial_clear():

void serial_clear(serial_t *obj) {
    obj->uart->FCR = 1 << 1  // rx FIFO reset
                   | 1 << 2  // tx FIFO reset
                   | 0 << 6; // interrupt depth
}

I never see this API being called from any code in the mbed SDK but if it was called, wouldn't it end up disabling the FIFO as it does not keep bit 0, the FIFO enable bit, set high?

Thanks for the report! I'll fix this.
