Question:

What is the Host Interface function (HIF) included in SH7618/SH7619?

Answer:

The HIF function is a 16-bit bus interface to connect with external devices. As it is independent from the local bus of SH7618/7619, it can be connected with external devices which do not share the local bus. In addition, the HIF allows external devices directly to read from and write to 2kbytes (1 kbyte x 2 banks) of the on-chip RAM exclusively for HIF use (HIFRAM) within this LSI.
The HIF supports high-speed data transfer from a main MCU such as transfer of data downloaded via Ethernet and the HIF boot mode allowing SH7618 to be booted, using HIFRAM.
