Pin Descriptions
All AT8xC51SND1C signals are detailed by functionality in Table 1 through Table 14.
Table 1. Ports Signal Description
Signal
Name
Type Description
P0.7:0
Port 0
P0 is an 8-bit open-drain bi-directional I/O port. Port 0 pins that have 1s
I/O written to them float and can be used as high impedance inputs. To
avoid any parasitic current consumption, floating P0 inputs must be
polarized to VDD or VSS.
P1.7:0
I/O
Port 1
P1 is an 8-bit bi-directional I/O port with internal pull-ups.
