- Bit 4—wdtimer_source: User watchdog timer timeout.
- Bit 3—nconfig_source: External configuration reset (nCONFIG) assertion.
- Bit 2—runconfig_source: Configuration reset triggered from logic array.
- Bit 1—nstatus_source: nSTATUS asserted by an external device as the result of an error.
- Bit 0—crcerror_source: CRC error during application configuration.
The POR value for all bits are 0. |

Watchdog Timeout Value |
12 |
Width of 12 when writing. The 12 bits for writing are the upper 12 bits (left-most or most-significant bits) of the 29-bit Watchdog Timeout Value. When writing parameter data, data_in[11..0] corresponds to the upper 12 bits of the 29-bit Watchdog Timeout Value. For example, to set the Watchdog Timeout Value to 1, write the 12 bits of data_in[11..0] as 12'b000000000001. |
| 29 |
Width of 29 when reading. |

24 or 32 |
For the Quartus® Prime software version 13.1 and later:
- Width of 24 or 32 when reading and writing the start address.
- For active serial devices using 24-bit addressing, such as EPCS128 or EPCQ128, PGM[23..2] corresponds to the upper 22 bits of the 24-bits start address. PGM[1..0] is read as 2'b0.
- For active serial devices using 32-bit addressing, such as EPCQ256, PGM[31..2] corresponds to the upper 30 bits of the 32-bits start address. PGM[1..0] is read as 2'b0.
For the Quartus® Prime software version 13.0 and earlier:
- Width of 24 when reading and writing the start address.
- For Arria® II and Stratix® IV devices, PGM[23..0] form the 24-bit start address.
- For Arria® V, Cyclone® V, and Stratix® V devices, if you use active serial devices using 24-bit addressing, such as EPCS128 or EPCQ128, PGM[23..0] corresponds to the 24 bits of the start address. If you use active serial devices using 32-bit addressing, such as EPCQ256, PGM[23..0] corresponds to the 24 MSB of the start address, thus the 32 bits start address is PGM[23..0],8'b0.

Configuration Mode (AnF) |

This parameter is set to 1 in application page and is set to 0 in factory page. In remote update mode, this parameter can be read and written. Before loading the application page in remote update mode, Intel® recommends that you set this parameter to 1. The content of the control register cannot be read properly if you fail to do so. |
