Watchdog Control register | |
This register bits control the prescaler, WD/Timer mode, Intr enable, auto-reload, watchdog enable. | |
| #define | XSCUWDT_CONTROL_PRESCALER_MASK 0x0000FF00U |
| Prescaler. More... | |
| #define | XSCUWDT_CONTROL_PRESCALER_SHIFT 8U |

Interrupt Status register | |
This register indicates the Counter register has reached zero in Counter mode. | |
| #define | XSCUWDT_ISR_EVENT_FLAG_MASK 0x00000001U |
| Event flag. More... | |
Reset Status register | |
This register indicates the Counter register has reached zero in Watchdog mode and a reset request is sent. | |
| #define | XSCUWDT_RST_STS_RESET_FLAG_MASK 0x00000001U |
| Time out occurred. More... | |
Disable register | |
This register is used to switch from watchdog mode to timer mode. The software must write 0x12345678 and 0x87654321 successively to the Watchdog Disable Register so that the watchdog mode bit in the Watchdog Control Register is set to zero. | |
