This subsection describes the memory map and registers for the
watchdog timer. The watchdog timer has a base address of
0x00c7_0000.
Refer to
The watchdog timer programming model consists of these registers:
1. S = CPU supervisor mode access only. S/U = CPU supervisor or user mode access. User
0x00c7_0000
0x00c7_0002
0x00c7_0004

For More Information On This Product,
The Watchdog Control Register (WCR) configures watchdog timer
operation. See
The Watchdog Modulus Register (WMR) determines the timer
modulus reload value. See
Register.
The Watchdog Count Register (WCNTR) provides visibility to the
watchdog counter value. See
Register.
The Watchdog Service Register (WSR) requires a service
sequence to prevent reset. See
Register.
