ADDRESSING BOTH OUTPUT LINES WITH ONE SIO COMMAND:
- Set the type parameter to 255 and the bank parameter to 2.
- The value parameter must then be set to a value between 0… 255, where every bit represents
one output line.
- Furthermore, the value can also be set to -1. In this special case, the contents of the lower 8 bits
of the accumulator are copied to the output pins.
Example:
Set all output pins high.
