Section 19 Electrical Characteristics
Table 19.2 Recommended Timing at Power-On
Note:
The time over which the internal state is undefined means the time taken to reach V
The pin states become settled when V
reset (RES) is normally accepted is after V
(when using the on-chip oscillator).
Ensure that the time over which the internal state is undefined is less than or equal to 100 ms.
