After self-refreshing has been specified, the SDRAM stays in the self-refresh state even after
this LSI enters the standby state. The self-refresh state continues after recovery from the
standby state by interrupt. However, the CKE and other pins must be driven in the standby
state by setting the HIZCNT bit in the CMNCR register to 1.
The self-refresh state is not cleared by a manual reset.
In case of a power-on reset, the bus state controller’s registers are initialized, and therefore the
self-refresh state is cleared.
