PortsAB
The highly flexible A and B ports are similarly structured
The Port A (see
Figure 11 ) consists of a data register and a
direction register Port B (see
Figures 12 thru Figure 14 ) has
an alternate function register in addition to the data and
direction registers All the control registers are readwrite
registers
The associated direction registers allow the port pins to be
individually programmed as inputs or outputs Port pins se-
lected as inputs are placed in a TRI-STATE mode by reset-
ting corresponding bits in the direction register
A write operation to a port pin configured as an input causes
the value to be written into the data register a read opera-
tion returns the value of the pin Writing to port pins config-
ured as outputs causes the pins to have the same value
reading the pins returns the value of the data register
Primary and secondary functions are multiplexed onto Port
B through the alternate function register (BFUN) The sec-
ondary functions are enabled by setting the corresponding
bits in the BFUN register
