Can I access HIFRAM externally when SH7618 is in standby mode?

Latest Updated:03/23/2009


When SH7618 is in the software standby mode, can its internal RAM for HIF (HIFRAM) be accessed from an external device?


No, it is impossible to access the HIFRAM from the external device in the software standby mode.
As the circuit which synchronizes the HIF control pin does not operate in the software standby mode, the access from the external device is not accepted.
Please access the HIFRAM after releasing the software standby mode by interruption (NMI, IRQ) or a reset.
