When interlock first out output I_FIRST_OUT is nonzero, it resets to
zero when:
- The block reset is
triggered (RESET_D transitions from a zero value to a non-zero value), or
- There is no longer an
active or latched interlock condition (all I_L_OUT_Dn = 0) and CMD_IN_D
changes.
If CMD_IN_D status is bad, I_FIRST_OUT does not reset automatically and
it must be reset manually.
After a reset, I_FIRST_OUT remains zero until the next trap occurs.
When the value of I_FIRST_OUT is zero, its status is GoodNonCascade.
