3.8.2 I/O Pad VDD33 Current Specifications
The power consumption of the VDD33 supply dependents on the usage of the pins on all I/O segments.
The power consumption is the sum of all input and output pin VDD33 currents for all I/O segments. The
output pin VDD33 current can be calculated from Table 11 based on the voltage, frequency, and load on
all fast (pad_fc) pins. The input pin VDD33 current can be calculated from Table 11 based on the voltage,
frequency, and load on all pad_sh and pad_sh pins. Use linear scaling to calculate pin currents for voltage,
frequency, and load parameters that fall outside the values given in Table 11.
