Maxim Integrated 6-7

Bits 7:0: Port 4 Input Bits. The read values of these bits reflect the logic states present at port 4 pins P4.0 to P4.7.

Bits 7:0: Port 5 Input Bits. The read values of these bits reflect the logic states present at port 5 pins P5.0 to P5.7.

Bits 7:0: Port 6 Input Bits. The read values of these bits reflect the logic states present at port 6 pins P6.0 to P6.5.

Bits 7:0: Input/Output Direction for Port 0. The bits in this register control the input/output direction for port pins P0.0

to P0.7. When PD0.n is set to 0, the corresponding port pin (P0.n) acts as an input with characteristics determined by

PO0.n. When PD0.n is set to 1, the port pin acts as an output, driving the output state given by PO0.n.
