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 KSZ8851-16MLLJ will set RX interrupt (bit 13
in ISR) when the number of received bytes in RXQ buffer exceeds the threshold set in this
register.
Interrupt Enable Register (0x90 – 0x91): IER
This register enables the interrupts from the QMU and other sources.
