Technical Description Application Programmers Interface (API) Most modern operating systems do not allow direct hardware access. The SeaIO driver and API have been included to provide control over the hardware in Windows and Linux environments. The purpose of this section of the manual is to help the customer with the mapping of the API to the actual inputs for the 8005 specifically. Complete documentation of the API can be found in its accompanying help file. Presetting an Output

Technical Description Port C Port C is written and read to as a single eight bit port, but it has the ability to be configured as two four bit ports. If both lower and upper nibbles are configure the same then no special considerations need to be made. But if they are configured differently, one nibble as input, and one as output then the user will have to keep this in mind. When reading, the input will be returned on the corresponding upper or lower nibble while the current outputs will
