| 78 | Integer, representing the value of DRCTL, the register controlling | |
| 79 | the SPI_READY handling. Note that to enable the DRCTL consideration, | |
| 80 | the SPI_READY mode-flag needs to be set too. | |
| 81 | Valid values are: 0 (disabled), 1 (edge-triggered burst) and 2 (level-triggered burst). | |
