If L6460 is not configured as slave device a current source IOUT will be active on this pin,

while the current sink IINP will be disabled. If L6460 is configured as a Slave device, the

current sink IINP will be active until nAWAKE pin is detected high for the first time; after that

both current sources IINP and IOUT will be disabled and the nAWAKE pin can be considered

as a digital input.

Here below is reported the nAWAKE pin simplified schematic.
