• Order of turning on 1.9 V power (Vcc, Vcc-PLL1, Vcc-PLL2, Vcc-RTC) and 3.3 V power
(VccQ, AVcc, AVcc_USB):
1. First turn on the 3.3 V power, then turn on the 1.9 V power within 1 ms. This interval
should be as short as possible.
2. Until Voltage is applied to all power supplies, a low level is input at the RESETP pin and, a
maximum of 4 CKIO clock cycles have been generated, internal circuits remain unsettled,
and so pin states are also undefined. The system design must ensure that these undefined
states do not cause erroneous system operation.
Note that the RESETP pin will not accept low level input while the CA pin is low level.
3. The state of pins MD5 to MD0 should be established after power supply startup and
maintained until after the RESETP pin is negated. Read-in of pins MD5 to MD0 is always
performed while the RESETP pin is asserted.
Waveforms at power-on are shown in the following figure 32.1.
