Description
directly connect to the DP pin of the USB connector; if the
carkit feature is not used, this pin can be connected to ground
output of the voltage regulator; place a 0.1 F capacitor
between this pin and ground
input; sets default operation mode of the ISP1302:
Operation mode can be changed after reset by changing the
value of the Mode register bits.
this pin can be programmed as:
OE_N input — Enables driving DP and DM when in USB
mode
INT_N output — Indicates interrupt when bit OE_INT_EN = 1
and SUSPEND_REG = 1
bidirectional; push-pull input; 3-state output
analog audio input signal for the left speaker channel; connect
to ground if not in use
analog audio input signal for the right speaker channel or audio
output signal for the microphone channel; connect to ground if
not in use
differential receiver output; reflects the differential value of DP
and DM
push-pull output
SE0 input and output — SE0 functions in DAT_SE0 USB
mode
VM input and output — VM functions in VP_VM USB mode
TxD input — UART mode
bidirectional; push-pull input; 3-state output
DAT input and output — DAT functions in DAT_SE0 USB
mode
VP input and output — VP functions in VP_VM USB mode
RxD output — UART mode
bidirectional; push-pull input; 3-state output

If a LOW is latched on reset (including power-on reset),
default mode is UART with 2.8 V signaling.
If a HIGH is latched on reset (including power-on reset),
default mode is USB with 3.3 V signaling.
