3.3.4. Setting Reset Time t
The programmable reset timer is triggered when the states of the signals applied to R1–R4 cause the associated
logic expression in Table 11 to go high (transition to the TRUE state).
Because this timer is re-triggerable, R1–R4 must remain TRUE for the duration of the desired t
Figure 14. Should R1–R4 transition FALSE during t
measurement accuracy due to higher integrator offset error.
