BA + 12: Digital I/O Port 0 (Read/Write 8-bit)
This port transfers the 8-bit Port 0 digital input/output data between the module and external devices. The
bits are programmed as input or output in groups of 4 (P0.0 - P0.3 and P0.4 - P0.7) by writing to the Direction
Register at BA + 15. For all bits set as inputs, a read reads the input values and a write is ignored. For all bits
set as outputs, a read reads the last value sent out on the line and a write writes the current loaded value out to
the line.
Note that when any reset of the computer is performed , all digital lines are reset to inputs and their
corresponding output registers are cleared.
BA + 13: Digital I/O Port 1 (Read/Write 8-bit)
This port transfers the 8-bit Port 1 digital input/output data between the module and external devices. The
bits are programmed as input or output in groups of 4 (P1.0 - P1.3 and P1.4 - P1.7) by writing to the Direction
Register at BA + 15. For all bits set as inputs, a read reads the input values and a write is ignored. For all bits
set as outputs, a read reads the last value sent out on the line and a write writes the current loaded value out to
the line.
Note that when any reset of the computer is performed , all digital lines are reset to inputs and their
corresponding output registers are cleared.

BA + 14: Digital I/O Strobe Select (Read/Write 8-bit)
This register is used to select the strobe source for the digital inputs when either Port 0 or Port 1 is
programmed for latch mode. Both Port 0 and Port 1 must use the same strobe signal. Reading this register
returns the current settings.
