Table 13-322 shows some common scenarios of how the error pin status and the values of two associated registers, Error Pin Control Register (Base Address + 0x40) and Error Pin Status Register (Base Address + 0x44), will correspond.
Scenario | Error Pin State Value | ESM_PIN_CTRL[3-0] KEY | ESM_PIN_STS[0] VAL status value | Additional Notes |
---|---|---|---|---|
POR Asserted | 0 | N/A | N/A | Registers are inaccessible. Device disables the I/O and pulls down internally. |
After de-assertion of POR | 1 | 0x0 (Normal Mode) | 0x0 | - |
After de-assertion of Warm Reset (error was not asserted when reset asserted) | 1 | 0x0 (Normal Mode) | 0x0 | - |
After de-assertion of Warm Reset (error was asserted when reset asserted) | 0 | 0x0 (Normal Mode) | 0x1 | - |
Force error pin | 0 | 0xA (Force Error Mode) | 0x0 | Forcing error on the pin via software. |
