TPRTY | Input | H22 | UTOPIA Transmit bus parity (TPRTY) signal. |
|
|
| The transmit parity (TPRTY) signal indicates the |
|
|
| parity of the TDAT[15:0] bus. A parity error is |
|
|
| indicated by a status bit and a maskable interrupt. |
|
|
| Cells with parity errors are inserted in the transmit |
|
|
| stream, so the TPRTY input may be unused. Odd or |
|
|
| even parity selection is made independently for |
|
|
| each channel using the RXPTYP register bit. |
|
|
| TPRTY is considered valid only when TENB is |
|
|
| simultaneously asserted and the |
|
|
| selected via TADR[4:0]. |
|
|
| TPRTY is sampled on the rising edge of TFCLK. |
|
|
|
|
TSOC | Input | J21 | UTOPIA Transmit Start of Cell (TSOC) signal. |
|
|
| The transmit start of cell (TSOC) signal marks the |
|
|
| start of cell on the TDAT bus. When TSOC is high, |
|
|
| the first word of the cell structure is present on the |
|
|
| TDAT bus. It is not necessary for TSOC to be |
|
|
| present for each cell. An interrupt may be |
|
|
| generated if TSOC is high during any word other |
|
|
| than the first word of the cell structure. |
|
|
| TSOC is considered valid only when TENB is |
|
|
| simultaneously asserted and the |
|
|
| selected via TADR[4:0]. |
|
|
| TSOC is sampled on the rising edge of TFCLK. |
