Input/Output Ports
There are 24 bidirectional input/output lines in the
micro-controller, labeled from PA to PC, which are
mapped to the data memory of [12H], [14H], [16H]
respectively. All of these I/O ports can be used for input
and output operations. For input operation, these ports
are non-latching, that is, the inputs must be ready at the
T2 rising edge of instruction MOV A,[m] (m=12H, 14H,
16H). For output operation, all the data is latched and
remains unchanged until the output latch is rewritten.
Each I/O line has its own control register (PAC, PBC,
PCC) to control the input/output configuration. With this
control register, CMOS output or Schmitt trigger input
with or without pull-high resistor structures can be
reconfigured dynamically (i.e. on-the-fly) under software
control. To function as an input, the corresponding latch
of the control register must write 1 . The input source
also depends on the control register. If the control
register bit is 1 the input will read the pad state. If the
control register bit is 0 the contents of the latches will
move to the internal bus. The latter is possible in the
Read-modify-write
CMOS configurations can be selected. These control
registers are mapped to locations 13H, 15H, 17H.
