Can any one tell me what all ports can be configured as general purpose I/O.
As per the data sheet it says that all the ports which are not being used for there predifined function can be used as general purpose I/O. But the data sheet doesnt specify exactly.
It just says
• General purpose I/O interface
— Up to 142 bits of general purpose I/O
— Coherent 32-bit control
— Bit manipulation supported via set/clear functions
— Unused peripheral pins may be used as extra GPIO
can any one pls help me understand this.
thanks in advance
