Toggling WDI for a period less than tWDT negatively affects IDD.
These specifications are beyond the recommended VDD range, and only define RESETn or RESETn output performance during VDD ramp up.
The lowest supply voltage (VDD) at which RESETn or RESETn becomes active; tRISE(VDD) ≥ 15 μs/V.
CTn (where n = 1, 2, 3, or 4) are constant current charging sources working from a range of 0 V to VTH(CTn), and the device is tested at VCTn = 0.5 V. For ICT performance between 0 V and VTH(CTn), see Figure 28.
