+NOTES
+-----
+### Tested on
+- PC-9801V
+- DIGITAL WAVE Dboard
+
+
+### RDY
+Current firmware does not control RDY line and it is drived as low to receive data always. While sending command firmware drive the line high.
+
+PC98 host keeps RDY line high to prevent keyboard from sending data while processing.
