7.6.10 Register 9 - Configuration port 1 register
7.6.9 Register 8 - Configuration port 0 register
This register configures the direction of the I/O pins. If a bit in this register is set (written
with logic 1), the corresponding port 0 pin is enabled as an input with high-impedance
output driver. If a bit in this register is cleared (written with logic 0), the corresponding
port 0 pin is enabled as an output. At reset, the device’s ports are inputs.
