10.3 INREQI
INREQI inputs H from the microcomputer when the input data is valid.
When INREQI=H and BFULLO=L, the IC fetches the input data to the internal buffer.
10.4 BFULLO
BFULLO outputs H when the internal buffer becomes FULL.
When INREQI=L and it is possible to become empty in an internal buffer, BFULLO outputs L.
