In the function division column, “HOST” stands for HOST IF, “SYS“SYSTEM, “CAM“CAMERA IF, “LCD“LCD IF, “AUD“Audio IF, “SD“SD Card IF,
“FL“NAND Flash IF, “TV“TV Encoder IF, “USB“USB IF, and “CLK“OSC&PLL.
In the power source system column, “1” stands for system 1 (VDDIO1), “2” for system 2 (VDDIO2), “3” for system 3 (VDDIO3), “4” for system 4 (VDDIO4), “A” for
system 5 (ADD).
”＊” in Active level column means active level can be changed by setting of register.
Init column is a pin state at the time of reset release.
*1 : RESETB=”L”
*2 : Pull-down only a test mode.
*3 : Suspend only a test mode.
*4 : Suspend or input only a test mode.
*5 : Suspend or Pull-down only a test mode.
*6 : Suspend, Pull-down or output function only a test mode.
*7 : Suspend, Pull-down or input function only a test mode.
*8 : Output or pull-down only a test mode.
*9 : Pull-down during CAMOFF mode.
*10 : The crystal oscillation circuit does not include a return resistance, so it is needed to examine an external circuit including return resistance.
*11 : I/O type is E at oscillation mode, it is G at external clock input mode.
*12 : When not during playback, the potential approximates Vref. Hi-Z at reset.
*13 : When disable reset, standby, anout_disable or mono_disable, pop noise occurs.
*14 : This pin outputs inverted signal of (R + L) / 2, If “monaural mode” is not selected. And outputs differential signal with L_OUT, If “monaural mode” is selected.
