Features
- up to 2048 I/O Pins
- I/O pin read and writes optimized for software bit-bang
- all memory accesses are on 32 bit boundaries
- output value can be bit 0, 7, 15 or 31 (assistance for software shift operations)
- output value can optionally be inverted
- tri-state control and output holding registers are treated the same
- tri-state control and output holding registers can be updated separately or with one write operation
- tri-state control and output holding registers can be read back
- I/O pin input "high" can be read as bit 0, 7, 15 or 15, or as 0xFFFFFFFF
- I/O pin input vale can be optionally inverted
- optional LED'S output port (maximum 32 LED's)
