Bit 7 = CEN: Counter enable.
This bit is ANDed with the Global Counter Enable
bit (GCEN) in the CICR register (R230). The
GCEN bit is set after the Reset cycle.
0: Stop the counter and prescaler
1: Start the counter and prescaler (without reload).
Note: Even if CEN=0, capture and loading will
take place on a trigger event.
Bit 6 = CCP0: Clear on capture.
0: No effect
1: Clear the counter and reload the prescaler on a
Bit 5 = CCMP0: Clear on Compare.
0: No effect
1: Clear the counter and reload the prescaler on a
Bit 4 = CCL: Counter clear.
This bit is reset by hardware after being set by
software (this bit always returns “0” when read).

Bit 3 = UDC: Up/Down software selection.
If the direction of the counter is not fixed by hard-
ware (TxINA and/or TxINB pins, see par. 10.3) it
can be controlled by software using the UDC bit.
0: Down counting
1: Up counting
Bit 2 = UDCS: Up/Down count status.
This bit is read only and indicates the direction of
the counter.
0: Down counting
1: Up counting
Bit 1 = OF0: OVF/UNF state.
This bit is read only.
0: No overflow or underflow occurred
1: Overflow or underflow occurred during a Cap-
Bit 0 = CS Counter Status.
This bit is read only and indicates the status of the
counter.
0: Counter halted
1: Counter running
