0x2 RESTART Force restart
0x3 RESET Force hard Reset (ignored if the timer/counter is enabled)

Bit 1 – LUPD: Lock Update

Lock Update

Locking the update ensures that all buffers are valid before an update is performed.

ValueDescription
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

Counter Direction

Normally this bit is controlled in hardware by the Waveform Generation mode or by event actions, but can also be changed from the software.

ValueDescription
0 The counter is counting up (incrementing)
1 The counter is counting down (decrementing)
