1. V_DD = 3.0 to 3.6 Vdc, V_SS = 0 Vdc, T_A = T_L to T_H, unless otherwise noted.
2. Typical values reflect average measurements at midpoint of voltage range, 25°C only.
3. Values are based on characterization results, not tested in production.
4. Guaranteed by design, not tested in production.
5. If minimum V_DD is not reached before the internal POR reset is released, the LVI will hold the part in reset until minimum
V_DD is reached.
6. R_PU is measured at V_DD = 3.3 V. Pullup resistors only available when PTAPUEx is enabled with KBIPx = 0.
7. R_PD is measured at V_DD = 3.3 V, Pulldown resistors only available when PTAPUEx is enabled with KBIPx =1.
