TUSB320: timing chart from CC detection until CURRENT_MODE_ADVERTISEMENT register bit transition

Hello,

Although we suggested to the customer to see INT_N pulling Low then read the I2C, he still requests the timing chart of that.

Could you prepare for the timing chart from CC detection to 0x08[7:6] CURRENT_MODE_ADVERTISE bit transition.

best regards,

Hi,

Let me look into this and see what we can provide here. Does the customer have some issue here? 

Thank you for your help.

To be honest, I do not know why he needs such an information though, I suppose this use for his software development. Please give him the timing chart from CC detection, CC Debounce, int_N, VBUS, I2C read timing.

best regards,

What is the port role here? Is TUSB320 powered from VBUS in this case?

port role is UFP. TUSB320 is powered from VBUS.

best regards,

sorry. The customer need both powered from VBUS and powered from built-in battery case.

let me recap the customer operating condition,

Port role : UFP

Power supply : VBUS power supply and built-in battery power supply.

best regards,

I will get you back to by 10.8 on this. need some time to create diagrams. 

Please see image attached below. T_I2C_READ is the delay set by the system/MCU to start I2C read of TUSB320LAI. It is optional and not required by TUSB320LAI. Image is not to scale.
