Note ⁽¹⁾: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be
guaranteed. The device should not be operated at these limits. The “Functional Specifications” table will
define the conditions for actual device operation. Exposure to absolute maximum rated conditions for
extended periods may affect device reliability.
Note ⁽²⁾: The frequency of PDR_A, NDR_B, PDR_C, and NDR_D outputs pulses, f_OP, is half of fosc value,
f_OP =(fosc/2).
