Individual port structures
Ports A, B, C, and D have some differences. The structure of each individual port is
described in the next sections.
Port A structure
Port A supports the following operating modes:
●
●
●
●
●
Port A also supports Open Drain/Slew Rate output drive type options using csiop Drive
Select registers. Pins PA0-PA3 can be configured to fast slew rate, pins PA4-PA7 can be
configured to Open Drain Mode.
See
Figure 84. Port A structure
Port pins PA0-PA3 are capable of Fast Slew Rate output drive option. Port pins PA4-PA7 are
capable of Open Drain output option.
