Watchdog Status and Control Register High
| WDOGEN | Enables or disables the WDOG’s operation 0 (0): WDOG is disabled. 1 (1): WDOG is enabled. |
| CLKSRC | Selects clock source for the WDOG timer and other internal timing operations. 0 (0): WDOG clock sourced from LPO . 1 (1): WDOG clock sourced from alternate clock source. |
| IRQRSTEN | Used to enable the debug breadcrumbs feature 0 (0): WDOG time-out generates reset only. 1 (1): WDOG time-out initially generates an interrupt. After WCT, it generates a reset. |
| WINEN | Enables Windowing mode. 0 (0): Windowing mode is disabled. 1 (1): Windowing mode is enabled. |
| ALLOWUPDATE | Enables updates to watchdog write-once registers, after the reset-triggered initial configuration window (WCT) closes, through unlock sequence 0 (0): No further updates allowed to WDOG write-once registers. 1 (1): WDOG write-once registers can be unlocked for updating. |
| DBGEN | Enables or disables WDOG in Debug mode. 0 (0): WDOG is disabled in CPU Debug mode. 1 (1): WDOG is enabled in CPU Debug mode. |
| STOPEN | Enables or disables WDOG in Stop mode. 0 (0): WDOG is disabled in CPU Stop mode. 1 (1): WDOG is enabled in CPU Stop mode. |
| WAITEN | Enables or disables WDOG in Wait mode. 0 (0): WDOG is disabled in CPU Wait mode. 1 (1): WDOG is enabled in CPU Wait mode. |
| TESTWDOG | Puts the watchdog in the functional test mode |
| TESTSEL | Effective only if TESTWDOG is set. Selects the test to be run on the watchdog timer. 0 (0): Quick test. The timer runs in normal operation. You can load a small time-out value to do a quick test. 1 (1): Byte test. Puts the timer in the byte test mode where individual bytes of the timer are enabled for operation and are compared for time-out against the corresponding byte of the programmed time-out value. Select the byte through BYTESEL[1:0] for testing. |
| BYTESEL | This 2-bit field selects the byte to be tested when the watchdog is in the byte test mode. 0 (00): Byte 0 selected 1 (01): Byte 1 selected 2 (10): Byte 2 selected 3 (11): Byte 3 selected |
| DISTESTWDOG | Allows the WDOG’s functional test mode to be disabled permanently 0 (0): WDOG functional test mode is not disabled. 1 (1): WDOG functional test mode is disabled permanently until reset. |
