Reset and Power AC Timing Specifications
The processor asserts the nRESET_OUT pin in one of several different modes:
Power on
Hardware reset
Watchdog reset
GPIO reset
Sleep mode
The following sections provide the timing and specifications for the entry and exit of these modes.
4.7.1
Power-On Timing
The external voltage regulator and other power-on devices must provide the processor with a
specific sequence of power and resets to ensure proper operation.
Timing” on page
31, shows this sequence and is detailed in
Specifications” on page
On the processor, it is important that the power supplies be powered up in a certain order to avoid
high current situations. The required order is:
1. VCCQ
2. VCCN
3. VCC and PLL_VCC
On the processor, it is important that the VCCQ power supply be powered up before or at the same
time as the VCCN power supply. The VCC and PLL_VCC power supplies may be powered up
anytime within the specification shown in
