Access:
This register can only be written if the bits WPSWS5 and WPHWS5 are cleared in
page
• FPOL: Fault Polarity (fault input bit varies from 0 to 5)
For each field bit y (fault input number):
• FMOD: Fault Activation Mode (fault input bit varies from 0 to 5)
For each field bit y (fault input number):
• FFIL: Fault Filtering (fault input bit varies from 0 to 5)
For each field bit y (fault input number):
CAUTION: To prevent an unexpected activation of the status flag FSy in the
bit FMODy can be set to “1” only if the FPOLy bit has been previously configured to its final value.
902
0 = The fault y becomes active when the fault input y is at 0.
1 = The fault y becomes active when the fault input y is at 1.
0 = The fault y is active as long as bit y of FPOL field is set.
1 = The fault y becomes active as soon as bit y of FPOL field is set. The fault y stays active until bit y of FPOL field is
unset AND until it is cleared in
0 = The fault input y is not filtered.
1 = The fault input y is filtered.
