14.3
14.3.1
The host interface is activated by setting the HIE bit (bit 1) to 1 in SYSCR, establishing slave
mode. Activation of the host interface (entry to slave mode) appropriates the related I/O lines in
port 3 or B (data), port 8 or 9 (control) and port 4 (host interrupt requests) for interface use.
For host interface read/write timing diagrams, see section 23.3.8, Host Interface Timing.
14.3.2
Table 14.5 indicates the slave operations carried out in response to host interface signals from the
host processor.
