X.86 Transmit and common Registers are used to control the operation of the X.86 encoder and decoder.
Register Name:
Register Description:
Register Address:
Bit #
Name
Default
Bit 0: X.86 Encoding Decoding (X86ED). If this bit is set to 1, X.86 encoding and decoding is enabled for the
Transmit and Receive paths. The MAC Frame is encapsulated in the X.86 Frame for Transmit and the X.86
headers are checked for in the received data. If X.86 functionality is selected, the X.86 receiver byte boundary is
provided by the RSYNC signal and the DS33Z41 provides the transmit byte synchronization TSYNC. No HDLC
encapsulation is performed.

Bits 7 to 0: X86 Transmit Receive Address (X86TRA7 to X86TRA0). This is the address field for the X.86
transmitter and for the receiver. The register default value is 0x04.

Default
Bits 7 to 0: X86 Transmit Receive Address (TRSAPIH7 to TRSAPIH0). This is the address field for the X.86
transmitter and expected for the receiver. The register is reset to 0xfe.
