Relationship between the Enable and RESET Inputs and Output Signals
Enable (ENn Pin)
Setting the ENn signal Low disables only the output block, and the internal circuitry continues to operate in
accordance with the CKn input. Therefore, when the ENn signal is set High again, the output current
restarts as if phases had proceeded with the CKn signal.
When ENn = Low, the output signals are disabled regardless of the state of the RESET signal.
Setting the RESET signal Low while ENn = Low resets the counter.
RESET (Serial Command)
Setting the RESET signal High causes the outputs to be put in the Initial state and the MOn output to be
driven Low.
When the RESET signal goes is set Low again, the output current generation restarts from the Initial state at
the next rising edge of CKn.
