These bits store the time-out value of the Watchdog Timer.
The scale of the timer is determine by the pre-scaler. The
timer can support a value of 150 ms to 4.8 sec when the
pre-scaler is set to 150 ms. If the prescaler is set to 2.5 sec,
it can support a value from 2.5 sec to 80 sec. When the
Watchdog Timer reaches “0,” it will set the WD_TO_STATUS
bit and generate Reset if RST_EN_WD is enabled.
Latched FS[4:0] inputs. These bits are read-only.
0 = Select operating frequency by FS[4:0] input pins
1 = Select operating frequency by SEL[4:0] settings
0 = 48-MHz output on pin 27
1 = 66-MHz output on pin 27
0 = 24-MHz
1 = 48-MHz
