In Table 6 – 16 , bit 2 in each control register ( CRA2 and CRB - 2 ) determines
selection of either an I / O port or the corresponding data direction register when
the proper register select signals are applied to RSO and RS1 . A 1 in bit 2 allows

In the uni - directional mode , a data direction register configures each port as an
input or output . In the bidirectional mode , the data direction registers are ignored
and the direction is determined by the state of four handshake pins .

There are six locations within the PIA accessible to the MPU data bus : two
Peripheral Registers , two Data Direction Registers , and two Control Registers .
Selection of these locations is controlled by the RSO and RS1 inputs together
with bit ...
