REV. P1.0.6
BIT [7:1] - Unused
BIT 0 - Transmit Erred A1 Byte Enable
This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 TOH Processor block to transmit a
continuous stream of STS-1 or STS-3 frames, in which the A1 byte is erred.
`
0 - Configures the Transmit STS-1/STS-3 TOH Processor block to NOT transmit STS-1 or STS-3 frames with erred
A1 bytes.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to transmit STS-1 or STS-3 frames with erred A1
bytes.
BIT [7:1] - Unused
BIT 0 - Transmit Erred A2 Byte Enable
This READ/WRITE bit-field is used to configure the Transmit STS-1/STS-3 TOH Processor block to transmit a
continuous stream of STS-1 or STS-3 frames, in which the A2 byte is erred.
`
0 - Configures the Transmit STS-1/STS-3 TOH Processor block to NOT transmit STS-1 or STS-3 frames with erred
A2 bytes.
`
1 - Configures the Transmit STS-1/STS-3 TOH Processor block to transmit STS-1 or STS-3 frames with erred A2
bytes.
BIT [7:0]B1 Byte Error Mask[7:0]
These READ/WRITE bit-fields are used to insert bit errors into the B1 bytes, within the outbound STS-1 or STS-3 Data
stream. The Transmit STS-1/STS-3 TOH Processor block will perform an XOR operation with the contents of the B1
byte, and this register. The results of this calculation will be inserted into the B1 byte position within the outbound STS-
1 or STS-3 Data stream. For each bit-field (within this register) that is set to 1, the corresponding bit, within the B1 byte
will be in error.
