About Touch Panel Interface at Interrupt Wait
Touch panel interface can switch to low power consumption by stopping the operation of unnecessary circuits at interrupt
wait.
Setting of touch panel interface at interrupt wait
0x2d = 0x00, // Thermal detect circuit Disable
0x1d = 0x02, // MAPCON=2
0x05 = 0x22, // Level shifter for headphone OFF
0x13 = 0x00, // Reference current circuit for audio system OFF
0x1d = 0x00, // MAPCON=0
0x0d = 0x80, // Touch panel interface oscillation circuit Enable
0x1d = 0x01, // MAPCON=1
0x61 = 0x38, // Touch panel interface interrupt circuit Enable
0x1d = 0x00, // MAPCON=0
0x0d = 0x00, // Touch panel interface oscillation circuit Disable
This state is interrupt wait mode. Please use a touch panel interface after interrupt, setting enable oscillation circuit.
Please, set circuit from Disable to Enable in circuit when using of audio system function
Setting at using of audio system function
0x2d = 0x01, // Thermal detect circuit Enable
0x1d = 0x02, // MAPCON=2
0x05 = 0x26, // Level shifter for headphone ON
0x13 = 0x01, // Reference current circuit for audio system ON
0x1d = 0x00, // MAPCON=0
