Address:
This register can only be accessed in test mode.
• TMEN: Test Mode Enabled
0: Test Mode Enabled.
1: Normal operation of Watchdog.
• WDRV: Watchdog Reset Value
When read, this bit contains the value of the watchdog reset output.
Writing to this register has no effect; it does not change the value which is read.
This bit is reset when a reset timeout occurs.
• WDIV: Watchdog Interrupt Value
When read, this bit contains the value of the interrupt output.
Writing to this register has no effect, it does not change the value which is read.
This bit is reset when a reset timeout occurs.
