Physical Address Upper Register (PAUR)
The application program writes the PAUR. This register contains the upper 16 bits (bytes 4 and 5) of the
48-bit MAC address used in the address recognition process to compare with the DA (destination address)
field of receive frames with an individual DA. In addition, this register is used in bytes 4 and 5 of the 6-byte
source address field when transmitting PAUSE frames. Bits 16:31 of the PAUR contain a constant TYPE
field (0x8808) used to transmit PAUSE frames. This register is not reset, and bits 0:15 must be initialized
by the application program. See
Section 15.4.10, “Full Duplex Flow Control
” for information on using the
TYPE field.
describes the fields and functions in the physical address upper register (PAUR):
15.3.4.2.13
Opcode and Pause Duration Register (OPD)
The OPD is read/write accessible. This register contains the 16-bit OPCODE and 16-bit pause duration
(PAUSE_DUR) fields used in transmission of a PAUSE frame. The OPCODE field is a constant value,
0x0001. When another node detects a PAUSE frame, that node pauses the transmission for the duration
specified in the pause duration field. This register is not reset and must be initialized by the application.
See
Section 15.4.10, “Full Duplex Flow Control
” for information on using the OPD register.
