14.1
The H8/3437 Series has an on-chip host interface (HIF) that provides a dual-channel parallel
interface between the on-chip CPU and a host processor. The host interface is available only when
the HIE bit is set to 1 in SYSCR. This mode is called slave mode, because it is designed for a
master-slave communication system in which the H8/3437-Series chip is slaved to a host
processor.
The host interface consists of four 1-byte data registers, two 1-byte status registers, a 1-byte
control register, fast A
