: Indicates the address bus, data bus, control signals, and serial signals of the SH7727.
Supply voltage is 3.3V.
*1: 5.0V (typ.) is supplied when the SH7727 is turned on.
*2: If this pin is set to "Low," output takes place from the SH7727 expansion to the expansion slot.
*3: 3.3V (typ.) is supplied when the AC adapter is connected.
*4: 3.3V (typ.) is supplied when the SH7727 is turned on.
*5: Pin for power supply (5.0V to 5.6V). T-Engine can be powered via the expansion slot.
