To program received frame duration timer threshold value in 1us interval. The maximum
value is 0xCFFF.
When bit 7 set to 1 in RXQCR register, the KSZ8851M will set RX interrupt (bit 13 in ISR)
after the time starts at first received frame in RXQ buffer and exceeds the threshold set in
this register.
Description
RXDBCT Receive Data Byte Count Threshold
To program received data byte threshold value in byte count.
When bit 6 set to 1 in RXQCR register, the KSZ8851M will set RX interrupt (bit 13 in ISR)
when the number of received bytes in RXQ buffer exceeds the threshold set in this
register.
