The SP3/SP4 serial port signals (UART TTL-level) are shared with the rear I/O option connector P4, and

must be used for one destination only in order to avoid signal interference. In addition, the PS/2

KB/MS signals are also shared with the rear I/O option connector P4, and must also be used for one

destination only. The audio signals (pins 35-44) are not in use on the C32-FIO mezzanine module.
