Functional Description
A CLRP command (i.e. setting bit PCTRL.CLRP) clears all sticky bits on the primary side. A CLRS command (i.e.
setting bit PCTRL.CLRS) clears all sticky bits on the secondary side.
Signals NFLTA and NFLTB are de-asserted with an invalid to valid transition of signal EN (in OPM3 or OPM5
only). Besides, they can be de-asserted by a CLRP command, depending on the device’ status.
In case bit PCFG.CLFAM is cleared, a CLRP command always deassert NFLTA. In case bit PCFG.CLFAM is set, a
CLRP command does not deassert NFLTA in the following cases:
• PSTAT2.FLTAP is set
• OR
• PSTAT2.ENVAL is cleared
In case bit PCFG.CLFBM is cleared, a CLRP command always deassert NFLTB. In case bit PCFG.CLFBM is set, a
CLRP command does not deassert NFLTB in the following cases:
• PSTAT2.FLTBP is set.
• OR
• bit PSTAT.SRDY is cleared
2.4.8
EN Signal Pin
The EN signal allows the logic on the primary side to have a direct control on the state of the device. A valid
signal has to be provided on this pin. A valid to invalid transition of the signal on pin EN generates an Event
Class A.
Pin EN should be driven actively by the external circuit. In case this pin is floating, an internal weak pull-down
resistor ensures that the signal is low.
Note:
It should be noted that even if the signal at pin EN is valid, the device can still be in disabled state.
This may happen for example if another error is being detected
A valid EN signal is defined as a digital High level. When EN is at Low level, the signal is considered as not valid
and the device is in Disabled State. In case of a High-to-Low transition, an Event Class A is generated.
An Invalid to Valid transition of signal EN deactivates signals NFLTA and NFLTB (when the device is in OPM3 or
OPM5 only).
The levels read by the device at pin EN is given by bits PPIN.ENL. The validity status of EN signal is given by bit
PSTAT2.ENVAL.
