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
