Section 9 Bus State Controller (BSC)
taken into consideration when setting the initial value of RTCNT. Making the RTCNT value 1 less
than the RTCOR value will enable refreshing to be started immediately.
After self-refreshing has been set, the self-refresh state continues even if the chip standby state is
entered using the LSI standby function, and is maintained even after recovery from standby mode
by an interrupt.
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.
