: Indicates the SH7760 address bus, data bus, control signal, and serial signal. The supply voltage is 3.3V.
*1: 5.0V (typ.) is supplied when the SH7760 is turned ON.
*2: When this pin is set to “Low,” output is made from the SH7760 extension bus to the extension slot.
*3: When a battery has been connected and an AC adapter is connected, 3.3V (typ.) is always supplied.
*4: When the SH7760 is turned ON, 3.3V (typ.) is supplied.
*5: Power supply pin (4.2V to 3.6V). This voltage is applied to Solution Engine2 via the extension slot.
