Section 7. Input/Output (I/O) Ports
7.1 Contents
7.2 Introduction
This section briefly describes the 31 input/output (I/O) lines arranged as
one 7-bit and three 8-bit ports. All of these port pins are programmable
as either inputs or outputs under software control of the data direction
registers.
NOTE:
To avoid a glitch on the output pins, write data to the I/O port data
register before writing a one to the corresponding data direction register.
7.3 Port A
Port A is an 8-bit bidirectional port which does not share any of its pins
with other subsystems. The port A data register is at $0000 and the data
direction register (DDR) is at $0004. The contents of the port A data
register are indeterminate at initial powerup and must be initialized by
user software. Reset does not affect the data registers, but clears the
data direction registers, thereby returning the ports to inputs. Writing a 1
to a DDR bit sets the corresponding port bit to output mode. A block
diagram of the port logic is shown in Figure 7-1.
