I/O Pads Power Supply and Signal Multiplexing Scheme
This section describes detailed information about both the power supply for each I/O pin and its function
multiplexing scheme. The user can reference information provided in Table 6 on page 18 to configure the
power supply scheme for each device in the system (memory and external peripherals). The function
multiplexing information also shown in Table 6 allows the user to select the function of each pin by
configuring the appropriate GPIO registers when those pins are multiplexed to provide different functions.

Test Function
TRISTATE
Forces all I/O signals to high impedance for test purposes. For normal operation, terminate this input
with a 1 k ohm resistor to ground. (TRI-STATE is a registered trademark of National Semiconductor.)
