Section 17 Host Interface [H8S/2138 Group]
17.3
17.3.1
The host interface is activated by setting the HI12E bit (bit 0) to 1 in SYSCR2 in single-chip
mode, establishing slave mode. Activation of the host interface (entry to slave mode) appropriates
the related I/O lines in port 3 (data), port 8 or 9 (control), and port 4 (host interrupt requests) for
interface use.
Table 17.5 shows HIF host interface channel selection and pin operation.

Table 17.6 indicates the slave operations carried out in response to host interface signals from the
host processor.
