PRODUCTION DATA
An SPMI target device communicates to the SPMI controller device and any other SPMI target devices, only if there is an internal error, which is not SPMI related. The target device initiates the error communication using Arbitration Request with A-bit as defined in the SPMI 2.0 specification. SPMI 2.0 protocol manages the situation with multiple target devices requesting error communication at the same time, by using the target arbitration process as described in SPMI 2.0 specification. Once the SPMI target device wins the arbitration using the A-bit protocol, it performs an Extended Register Write command to Group Target ID (GTID) address 1111 by using the protocol described in Section 8.4.2.2 for communicating PFSM trigger ID.
