I3C status error register
| CODERR | Protocol error code/type 0 (B_0x0): CE0 error (transaction after sending CCC): 1 (B_0x1): CE1 error (monitoring error): 2 (B_0x2): CE2 error (no response to broadcast address): 3 (B_0x3): CE3 error (failed controller-role hand-off): 8 (B_0x8): TE0 error (invalid broadcast address 0b111_1110 + W): 9 (B_0x9): TE1 error (CCC code): 10 (B_0xA): TE2 error (write data): 11 (B_0xB): TE3 error (assigned address during dynamic address arbitration): 12 (B_0xC): TE4 error (0b111_1110 + R missing after Sr during dynamic address arbitration): 13 (B_0xD): TE5 error (transaction after detecting CCC): 14 (B_0xE): TE6 error (monitoring error): |
| PERR | Protocol error 0 (B_0x0): no detected error 1 (B_0x1): whatever controller or target, hardware detected a protocol error, as detailed in CODERR[3:0] |
| STALL | SCL stall error (when the I3C acts as target) 0 (B_0x0): no detected error 1 (B_0x1): target detected that SCL was stable for more than 125 s during an I3C SDR data read (during a direct CCC read, a private read, or an IB) |
| DOVR | RX-FIFO overrun or TX-FIFO underrun 0 (B_0x0): no detected error 1 (B_0x1): whatever controller or target, hardware detected either: |
| COVR | C-FIFO underrun or S-FIFO overrun (when the I3C acts as controller) 0 (B_0x0): no detected error 1 (B_0x1): controller detected either: |
| ANACK | Address not acknowledged (when the I3C is configured as controller) 0 (B_0x0): no detected error 1 (B_0x1): controller detected that the static/dynamic address was not acknowledged by a target, either during: |
| DNACK | Data not acknowledged (when the I3C acts as controller) 0 (B_0x0): no detected error 1 (B_0x1): controller detected that a data byte is not acknowledged by a target, either during: |
| DERR | Data error (when the I3C acts as controller) 0 (B_0x0): no detected error 1 (B_0x1): controller detected a data error during the controller-role hand-off procedure (GETACCCR CCC, formerly known as GETACCMST) when the received target address or/and the parity bit do no match. Active controller keeps controller-role. |
