This register is to get analog-to-digital conversion data of the touch panel interface ADC. In the 12bit mode, please read
register in order of ADCR1 ($62h), ADCR2 ($64h).
TOUTCHAD1
This register is to get analog-to-digital conversion data of the touch panel interface ADC. In the 8 bit mode, please read
only this register. In the 12 bit mode, this register is higher 8 bits of the 12bit ADC output data.
TOUTCHAD2
This register is to get analog-to-digital conversion data of the touch panel interface ADC. In the 8 bit mode, this register
value is "0". In the 12 bits mode, this register is lower 4 bits of the 12bit ADC output data.

This register is to set the input path of the headphones amplifier. Please do not set HPRIN1EN bit and the HPRIN2EN bit
to "1" simultaneously. Please set only either bit to " 1 ".
HPLIN1EN
This bit is to set the input path of the Lch headphones amplifier.
HPLIN1EN
Explanation
0x0
Disconnect the output of Lch-DAC to Lch headphones amplifier.
0x1
Connect the output of Lch-DAC to Lch headphones amplifier.
HPRIN1EN
This bit is to set the input path of the Rch headphones amplifier.
HPRIN1EN
Explanation
0x0
Disconnect the output of Lch-DAC to Rch headphones amplifier.
0x1
Connect the output of Lch-DAC to Rch headphones amplifier.
HPRIN2EN
This bit is to set the input path of the Rch headphones amplifier.
HPRIN2EN
Explanation
0x0
Disconnect the output of Rch-DAC to Rch headphones amplifier.
0x1
Connect the output of Rch-DAC to Rch headphones amplifier.
