Transparency/Half Tone through an extra circuit.
I-pin output high for area plane 1, set PISEL1 (bit 3 in the ORACL register) to “1”.
If you want to make the I-pin output high for area plane 2, set PISEL2 (bit 7 in the
ORACL register) to “1”.
GIN, BIN, and Y/BLIN signals from external input.
This function is used to select either Y or BL signal output from the Y/BL pin.
Y/BL signal select register (1 bit) … YBLCS (bit 7 in ORP6S)
When PIDS (bit 3 in ORP6S) is set to “0”, Port 57 (I pin) can be used as Half
The I-pin output is made high only for the area planes. If you want to make the
