RX_TIMEOUT_VAL[1:0]
Variable Threshold dictates the minimum number of messages required to be in the RXFIFO
before an interrupt is generated. ‘000’ = 1 message ‘111’ = 8 messages.
These bits specify a variable delay, relative to a read from the receive message FIFO, in steps
of 125 us, before an interrupt is generated, if the Receive FIFO level is greater than 0. The
objective is to stop stale messages collecting in the RXFIFO.
