| High: the idle clock is at a high level. This is equivalent to CPOL=1. |
|
|
Clock Edge | Select the clock edge or clock phase (CPHA) for latching data: |
| First: each bit is latched on the first edge of the clock. This is equivalent to |
| CPHA=0. |
| Second: each bit is latched on the second edge of the clock. This is |
| equivalent to CPHA=1. |
