MB86R02 ‘Jade-D’ Hardware Manual V1.64
WDT issued reset. The host CPU should therefore detect abnormal operation of the MB86R02
and reacivate it itself.
16.5.1.4.6. Reactivation process
If the status is not returned because the AHB-BUS and the slave device are deadlocked, the host
CPU can insert an RST request in the CMD byte during transmission. The figure below shows
the deadlock reactivation process.

Figure 16-21 Deadlock reactivation process
The response from the HOSTIF module is monitored using the software timer which is managed
by the host CPU.
The MB86R02 is reactivated from a deadlock by asserting a RST from the host CPU if there has
been no response for a set time (e.g. for 0.5 seconds).
