19.2 Power-On and Power-Off Order
• Order of turning on 1.5-V system power (V_CC (main), V_CC (sub), V_CC (PLL1), and V_CC (PLL2))
and 3.3-V system power (V_CC Q)
 First turn on the 3.3-V system power, then turn on the 1.5-V system power within 1 ms.
This time should be as short as possible. The system design must ensure that the states of
pins or undefined period of an internal state do not cause erroneous system operation.
 Until voltage is applied to all power supplies and a low level is input to the RES pin,
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.
Waveforms at power-on are shown in the following figure.
