Note:
  1. When the WDTCCS in Configuration bits = ‘0b111, the Reset value of WDTCS is ‘b000.
  2. The Reset value (q) of WINDOW is determined by the value of WDTCWS in the Configuration bits.
  3. When the WDTCCS in Configuration bits ≠ ‘b111, these bits are read-only.
  4. When the WDTCWS in Configuration bits ≠ ‘b111, these bits are read-only.
