3.3.4. Setting Reset Time t_R
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_R as shown in
Figure 15. Should R1–R4 transition FALSE during t_R, integrator reset will be immediately halted, resulting in lower
measurement accuracy due to higher integrator offset error.
