详细说明：一款外置typec识别外置芯片，介绍了芯片的设计原理及其细节。PER/COM Enabling Serial Connectivity pplication Note 0x02 Control Bit 7= powersaving 0= Enable active state 1=Disable and low power state In Disable and low power state, all outputs of PIsUSB30216C, with the exception of CCl and cc2 pins, are in High-Z State. CCl and cc2 pins are pulled low with resistor Fd Bits[6]=Dual role 2 Iry. SRC or Iry. SNK settng 0=Enable Try. SRC supported 1= Enable Try SNC supported Bits []=Accessory Detection in Device Mode u=Disable = Enable Bits [4: 3]= Charging cuirent mode System can set the charging curent mode when port is a host or dual role acting as host. These bits are ignored when pout is a deuce or dual role ctng as device 00= Default curent mode 01= Medium current mode (1.5A) 10=High curent mode (3A) Bits [2: 1]=Port setting System can set the role of the port 00=Device(SNK 01= Host (SRO) 10=Dhal Role (drY 11=Dual Role 2 (DRP) where Try siC or Try SNC is supported Bit o= interrupt mask INTB pin i used to acknowledge syste if there is any interrupt events tnggered. When this bit is set to 0. In tB pin is pulled low when an interupt erent occur. When this bit is set to l, INTB pin ignores all interupt and remain High-Z 0=Do not mask interupt I=Mask interrupt 12C Transport API instead of 12c smbus" api to communicate with pi5UsB30216C if needed interrupt by writing a'1to Bit 0 of Control Register(0x02 ).
