During TSC2008 power up, an internal power-on reset (POR) is triggered if the power-supply ramping meets the
timing requirements shown in Figure 37 and listed in Table 9. The recommended and typical VDD off times are
shown in Figure 38. The POR brings the TSC2008 to the default working condition. If the system is not able to
meet the power ramping timing requirements, or if the system is not properly reset (even after a POR), then
including the SureSet reset in the initialization routine is recommended.
