PIN DESCRIPTIONS
The basic functions of each pin of the ML64168 is described in Table 1.
A symbol with a slash ( / ) denotes a pin that has a secondary function.
Refer to Table 2 for secondary functions.
For Type, “ - ” denotes a power supply pin, “ I ” an input pin, “O” an output pin, and “I/O” an input-
output pin.
