3.2.7. 1899433: PFG duplicate reported faults through a Warm reset

Description

Under certain conditions, the Pseudo-fault Generation Error Record Registers might generate duplicate faults through a Warm reset.

Conditions

  1. ERR0PFGCDN is set with a non-zero countdown value.
  2. ERR0PFGCTL is set to generate a pseudo-fault with ERR0PFGCTL.CDEN enabled.
  3. The countdown value expires, generating a pseudo-fault.
  4. Warm reset asserts.

Impact

After the Warm reset, a second generated pseudo-fault might occur.

Workaround

De-assert the ERR0PFGCTL control bits before asserting a Warm reset.
