Bits 3:2 – CMD[1:0] Command
This bit field is used for software control of update, restart, and Reset of the
timer/counter. The command bit field always reads as ‘0’.

| 0x1 | UPDATE | Force update |
| 0x2 | RESTART | Force restart |
| 0x3 | RESET | Force hard Reset (ignored if the timer/counter is enabled) |
Bit 1 – LUPD Lock Update
Locking the update ensures that all buffers are valid before performing an update.
| Value | Description |
|---|---|
| 0 | The buffered registers are updated as soon as an UPDATE condition has occurred |
| 1 | No update of the buffered registers is performed, even though an UPDATE condition has occurred. This setting will not prevent an update issued by the Command bit field. |
Bit 0 – DIR Counter Direction
Usually, this bit is controlled in hardware by the Waveform Generation mode or by event actions but can also be changed from the software.
| Value | Description |
|---|---|
| 0 | The counter is counting up (incrementing) |
| 1 | The counter is counting down (decrementing) |
