7.5 I/O Port Configuration Registers
The I/O mode for each bit of the three ports is
selected by using the Configuration Registers 4,
13 and 15 (See Table 7.1) The structure of these
registers is illustrated in the following tables.
Each bit of the configuration registers determines
the I/O mode of the related port pin.
