System Power Supply
*1 When L is input, Pull-UP turns OFF.
*2 BU94601KV / BU94603KV
*3 BU94604BKV
*4 When SD I/F is disused, pull-up to 3.3V system power supply.
*5 Enabled/Disabled can be selected using commands.
This pin becomes output and pull-up is OFF, only when 12MHz clock output is enable.
*6 In STAND ALONE MODE (MODE1),
When Audio Line output is selected (SEL_DOUT=H), LED output is enabled.
When the Digital Audio output is selected (SEL_DOUT=L), the I²S format audio output is enabled.
In SLAVE MODE (MODE2, MODE3),
When the Analog Line output is selected (SEL_DOUT=H), these pins are TEST terminals.
When the Digital Audio output is selected (SEL_DOUT=L), I²S or SPDIF is selectable.
See Chapter 4 . SEL_DOUT for further information.
*7 Input L level directly without resistance when you input L to the terminal with Pull-Up (about 33 kΩ).
