Output Driver Characteristics
This table provides information on the characteristics of the output driver strengths.
Note:
1. GVDD, NVDD, AVDD, and VDD must track each other and must vary in the same direction—either in the positive or negative direction.
2. Some GPIO pins may operate from a 2.5-V supply when configured for other functions.
3. Min temperature is specified with TA; Max temperature is specified with TJ.
4. All Power rails must be connected and power applied to the MPC8313 even if the IP interfaces are not used.
5. All I/O pins should be interfaced with peripherals operating at same voltage level.
6. This voltage is the input to the filter discussed in Section 22.2, “PLL Power Supply Filtering” and not necessarily the voltage at the
AVDD pin, which may be reduced from VDD by the filter.
