14.5.3.3.9
The MRBLR register is written by the user. It informs the eTSEC how much space is in the receive buffer
pointed to by the RxBD.
14.5.3.3.10 Receive Data Buffer Pointer High Register (RBDBPH)
The RBDBPH register is written by the user with the most significant address bits common to all RxBD
buffer addresses, RxBD[Data Buffer Pointer]. As a consequence, Rx buffers must be placed in a 4 Gbyte
segment of memory whose base address is prefixed by the bits in RBDBPH. The RxBD ring itself can

buffer. The MRBL register is written by the user with a multiple of 64 for all modes. The eTSEC can write fewer
bytes to the buffer than the value set in MRBL if a condition such as an error or end-of-frame occurs, but it
never exceeds the MRBL value; therefore, user-supplied buffers must be at least as large as the MRBL. MRBL
must be set, together with the number of buffer descriptors, to ensure adequate space for received frames.
See
To ensure that MRBL is a multiple of 64, these bits are reserved and should be cleared.

Destination IP address. If an IPv4 header was found, this is the entire destination address. If an IPv6
header was found, this is the 32 most significant bits of the 128-bit destination address. This value
defaults to 0x0000_0000 if no IP header appeared.
Source IP address. If an IPv4 header was found, this is the entire source address. If an IPv6 header was
found, this is the 32 most significant bits of the 128-bit source address. This value defaults to
0x0000_0000 if no IP header appeared.

Destination port number for TCP or UDP headers. This value defaults to 0x0000 if no TCP or UDP
headers were recognized.
Reserved, should be written with zero.
Source port number for TCP or UDP headers. This value defaults to 0x0000 if no TCP or UDP headers
were recognized.
