16 OUTPUT PORTS
Each I/O port line may be individually configured using one
of three mask options. The three I/O mask options are
specified below:
Option 1 Standard input/output with switched pull-up
current source; this is shown in Fig.34.
Option 2 Input/output with Open drain output; this is
shown in Fig.35.
Option 3 Push-pull output; this is shown in Fig.36.
The state of each output port after a Power-on-reset can
also be selected using the mask options. All port mask
options are given in Section 16.1.
