In all cases, the power-up sequence must follow the guidelines shown in Figure 8.
The following rules apply:
1.
During time interval A, VDDH should always be equal to or less than the VDD/VCCSYN voltage level.
The duration of interval A should be kept below 10 ms.
2.
The duration of timing interval B should be kept as small as possible and less than 10 ms.

Clock and Timing Signals
The following sections include a description of clock signal characteristics. Table 7 shows the maximum frequency values for
internal (Core, Reference, Bus, and DSI) and external (CLKIN and CLKOUT) clocks. The user must ensure that maximum
frequency values are not exceeded.
