GPIO Port  
1.6  
Configuration and Control  
Registers  
The GPIO module contains the data port (GPIO),  
internal pull up resistors and the Output Latches  
(OLAT).  
The Configuration and Control blocks contain the  
registers as shown in Table 1-3.  
Reading the GPIO register reads the value on the port.  
Reading the OLAT register only reads the OLAT, not  
the actual value on the port.  
Writing to the GPIO register actually causes a write to  
the OLAT. Writing to the OLAT register forces the  
associated output drivers to drive to the level in OLAT.  
Pins configured as inputs turn off the associated output  
driver and put it in high-impedance.
