Bits 15:8 – TBPRE[7:0] Timebase Prescaler
The value by which the oscillator frequency is divided to generate the timebase counter clock. Valid values for the timebase prescaler are 0 to 255. The actual interpretation by the hardware of this value is such that one more than the value programmed here is used. Affects only the TSU internal timebase.
Bit 2 – SCP Select Capturing Position
| Value | Description |
|---|---|
| 0 | Timestamp captured at EOF |
| 1 | Timestamp captured at SOF |
Bit 1 – TCBS Timebase Counter Select
No external timebase is connected. Set TBCS to 0.
| Value | Description |
|---|---|
| 0 | Timestamp value captured from internal timebase counter (32 bits) |
| 1 | Timestamp value captured from external timebase counter (32 bits) |
Bit 0 – TSUE Timestamp Unit Enable
| Value | Description |
|---|---|
| 0 | TSU disabled |
| 1 | TSU enabled |
