3.2.1 Power Supply Select Jumpers (JP1 and JP2)

The SH7206 uses 3.3V and 1.25V power supply voltages. The JP1 and JP2 allow the sources for the SH7206

power supply voltages (3.3V and 1.25V) to be selected.

Figure3.2.2 shows the SH7206 Power Supply Voltage Select Jumpers Assignment (JP1 and JP2).

Table3.2.1 and Table3.2.2 list jumper settings for selecting SH7206 power supply voltage.
