PIO Interrupt Force Register (DWC_mipi_i3c_HCI_block.PIO_INTR_FORCE) – Offset ec
The PIO Interrupt Force register is used to force specific interrupt. It can be used for debug purposes.
| Bit Range | Default | Access | Field Name and Description |
|---|---|---|---|
| 31:10 | 0h | RO | Reserved |
| 9 | 0h | WS | (TRANSFER_ERR_FORCE) For software testing, when TRANSFER_ERR_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 8:6 | 0h | RO | Reserved |
| 5 | 0h | WS | (TRANSFER_ABORT_FORCE) For software testing, when TRANSFER_ABORT_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 4 | 0h | WS | (RESP_READY_FORCE) For software testing, when RESP_READY_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 3 | 0h | WS | (CMD_QUEUE_READY_FORCE) For software testing, when CMD_QUEUE_READY_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 2 | 0h | WS | (IBI_THLD_FORCE) For software testing, when IBI_THLD_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 1 | 0h | WS | (RX_THLD_FORCE) For software testing, when RX_THLD_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
| 0 | 0h | WS | (TX_THLD_FORCE) For software testing, when TX_THLD_FORCE set to 1'b1, forces the corresponding interrupt, subject to INTR_STAT_EN and INTR_SIGNAL_EN configuration. |
