After the HBC has started, software must then poll the OCFLAG
for a high pulse and restore the DAT0 register and the START
signal to continue with the next data transmission.

If software is to proceed with another data transmission, the
OCFLAG must be zero before polling for the next OCFLAG high
pulse. However, since the specification in the example requires no
other data transmission software can proceed as desired.
