Up to eleven 8-bit I/O ports are implemented. For 128-pin options, ports P1 to P10 are complete, and port P11 is 6 bits wide. For 100-pin options, ports P1 to P7 are complete, port P8 is 2 bits wide, and ports P9, P10, and P11 are completely removed. Port PJ contains four individual I/O pins, common to all devices. All I/O bits are individually programmable.
