Ports
67
to
60
I/O 8-bit input-output port (port 1): input or output can be selected for
each bit by the port 1 direction register (P1DIR). In addition to their
input or output port functions, the pins of port 1 have secondary
functions: see Secondary Function.
Control
87
I
System reset input: when this pin goes low, the internal state of
the chip is initialized and program execution restarts from address
0040H. The input is pulled up to VDD with an internal pull-up
resistor.
76
to
69
I/O 8-bit input-output port (port 0): input or output can be selected for
each bit by the port 0 direction register (P0DIR). In addition to their
input-output port functions, the pins of port 0 have secondary
functions: see Secondary Function.
86
to
82
I/O 5-bit input-output port (port 2): input or output can be selected for
each bit by the port 2 direction register (P2DIR). In addition to their
input or output port functions, P2.0 and P2.1 have secondary
functions: see Secondary Function.
22
to
29
I
8-bit input port (port3): during A/D conversion, the pins of port 3
function as analog input channels.
51
to
44
I/O 8-bit input-output port (port 4).
43
to
36
I/O 8-bit input-output port (port 5): input or output can be selected for
each bit by the port 5 direction register (P5DIR).
