This 16-bit parallel host interface allows the
CS98100 to be a host master, controlling other de-
vices that would be used on the same system. The
interface supports a programmable protocols and
speeds, including multiplexed and non-multiplexed
addressing. Slaves with different protocols can be
connected at the same time, controlled by different
