7.4.3 Polarity inversion registers (04h, 05h)
7.4.4 Configuration registers (06h, 07h)
The Polarity inversion registers (registers 4 and 5) allow polarity inversion of pins defined
as inputs by the Configuration register. If a bit in these registers is set (written with ‘1’), the
corresponding port pin’s polarity is inverted in the input register. If a bit in this register is
cleared (written with a ‘0’), the corresponding port pin’s polarity is retained. A register pair
write is described in
Table 11.
Table 12.
The Configuration registers (registers 6 and 7) configure the direction of the I/O pins. If a
bit in these registers is set to 1, the corresponding port pin is enabled as a
high-impedance input. If a bit in these registers is cleared to 0, the corresponding port pin
is enabled as an output. A register pair write is described in
read is described in
Table 13.
