Section 15 Host Interface (HIF)
15.6
Figure 15.3 shows the basic read/write sequence. HIF read is defined by the overlap period of the
HIFRD low-level period and HIFCS low-level period, and HIF write is defined by the overlap
period of the HIFWR low-level period and HIFCS low-level period. The HIFRS signal indicates
whether this is normal access or index/status register access; low level indicates normal access and
high level indicates index/status register access.
