The number of WTHRHLR registers depends on num_watchdog generic parameter
configuration. In case num_watchdog is zero, these registers are not implemented.
The length of the threshold field depends on the generic resolution.
36.5.1.18 Internal Channel Watchdog Select Registers (ICWSELR0–ICWSELR11)
These registers contain WSEL_CHx[3:0] bitfields to select the threshold register which
provides the values to be used for upper and lower bounds for channel x.
The Watchdog select registers to channel association is described in
