FUNCTIONAL DEVICE OPERATION
LOGIC COMMANDS AND REGISTERS
Description: This register is split into 2 sub registers, TIM1 and TIM2.
TIM1 controls the watchdog timing selection as well as the window or timeout option. TIM1 is selected when bit D3 is 0.
TIM2 is used to define the timing for the cyclic sense and forced wake-up function. TIM2 is selected when bit D3 is 1.
No read operation is allowed for registers TIM1 and TIM2
