Hi-Z Mode
(Mode1 = 0 and Mode0 = 0)
Q1, Q2, and Q3 (
Figure 12-1
) are OFF. The GPIO pin is not driven internally. Performing a read from the Port Data Register
return the actual logic value on the port pins.
Low Sink Mode
(Mode1 = 1, Mode0 = 0, and the pin’s Data Register = 0)
Q1 and Q3 are OFF. Q2 is ON. The GPIO pin is capable of sinking 2 mA of current.
Medium Sink Mode
(Mode1 = 0, Mode0 = 1, and the pin’s Data Register = 0)
Q1 and Q3 are OFF. Q2 is ON. The GPIO pin is capable of sinking 8 mA of current.
High Sink Mode
(Mode1 = 1, Mode0 = 1, and the pin’s Data Register = 0)
Q1 and Q3 are OFF. Q2 is ON. The GPIO pin is capable of sinking 50 mA of current.
High Drive Mode
(Mode1 = 0 or 1, Mode0 = 1, and the pin’s Data Register = 1)
Q1 and Q2 are OFF. Q3 is ON. The GPIO pin is capable of sourcing 2 mA of current.
Resistive Mode
(Mode1 = 1, Mode0 = 0, and the pin’s Data Register = 1)
Q2 and Q3 are OFF. Q1 is ON. The GPIO pin is pulled up with an internal 14-k
resistor.
Note that open drain mode can be achieved by fixing the Data and Mode1 Registers LOW, and switching the Mode0 register.
Input thresholds are CMOS, or TTL as shown in the table (See Section 25.0 for the input threshold voltage in TTL or CMOS
modes). Both input modes include hysteresis to minimize noise sensitivity. In suspend mode, if a pin is used for a wake-up
interrupt using an external R-C circuit, CMOS mode is preferred for lowest power.
12.1
Port 2 serves as an auxiliary input port as shown in
Figure 12-8
. The Port 2 inputs all have TTL input thresholds.

Bit [5:4]: D+ (SCLK) and D– (SDATA) States
The state of the D+ and D– pins can be read at Port 2 Data Register. Performing a read from the port pins returns their logic
values.
1 = Port Pin is logic HIGH
0 = Port Pin is logic LOW
