Functional Block Description
Type 1 and other accessories will not be affected by the RAW DATA bit. LKR and the button bits will not set when RAW DATA = 0.
The period of ADC conversion is determined by the Device Wake-up bits in the Timing Set 1 register. All other behaviors of Audio
Type 1 and other accessories will not be affected by the RAW DATA bit.

Analog and Digital Switches
The signal switches in the MC34708 are shown in Figure 26 . These switches are controlled by the identification result when the
Manual S/W = 1, and by the Manual SW/Result register, when the Manual S/W = 0 is in Active mode. The Switch_Open bit
overrides the switch configuration. When the Switch_Open bit is 0, all switches are turned off. The switches for the SPK_L and
SPK_R are capable of passing signals of ? 1.5 V, referencing to the GND pin voltage. The SPK_L and SPK_R pins are pulled
down to GND via a 100 k ? resistor respectively, as shown in Figure 26 . When the switches are configured automatically by the
identification result, the configuration of the switches vs. the device type is shown in Table 93 .
When detachment of an accessory is detected, the MC34708 will return to Standby mode. In Standby mode, regardless of the
Manual S/W = 1 or Manual S/W = 0 state, all signal switches and are off in the Standby mode. The OUT-to-ground FET is turned
on whenever the FET_ON bit is '0'.
