RX Frame Data Pointer Register (0x86 – 0x87): RXFDPR
The value of this register determines the address to be accessed within the RXQ frame buffer. When the Auto Increment
is set, it will automatically increment the RXQ Pointer on read accesses to the data register.
The counter is incremented is by one for every byte access, by two for every word access, and by four for every double
word access.
0x88 – 0x8B: Reserved
RX Duration Timer Threshold Register (0x8C – 0x8D): RXDTTR
This register is used to program the received frame duration timer threshold.

RXFPAI RX Frame Pointer Auto Increment
When this bit is set, the RXQ Address register increments automatically on accesses to
the data register. The increment is by one for every byte access, by two for every word
access, and by four for every double word access.
When this bit is reset, the RX frame data pointer is manually controlled by user to access
the RX frame location.
Reserved.
WST Write Sample Time
This bit is used to select the WRN active to write data valid time as shown in Figure 11.
0: WRN active to write data valid sample time is range of 8nS (min) to 16nS (max).
1: WRN active to write data valid sample time is 4nS (max).
EMS Endian Mode Selection
This bit is used to select either Big or Little Endian mode when Endian mode select
strapping pin (10) is NC or tied to GND.
0: is set to Little Endian Mode
1: is set to Big Endian Mode
RXFP RX Frame Pointer
RX Frame data pointer index to the Data register for access.
This pointer value must reset to 0x000 before each DMA operation from the host CPU to
read RXQ frame buffer.
Description
RXDTT Receive Duration Timer Threshold
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 KSZ8851-16MLLJ 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.
