1: DFP is down stream port like USB host, UFP is upstream port and DRP can act both DFP and UFP, like USB otg.

2: it will be handled by software to make TUSB422 to charge and discharge.

3: for BQ25713, pls submit a separate E2E ticket and it will go to right group

hi,

TUSB422

1. ALERT register and CC_STATUS registers are used to find the interrupt and which device connected either Charger or Device,

2. as mobile phone is connected in TUSB422 Role control is written as 0x05 or0x15 or0x25

3. 01110111 command is written in command register

is this correct?

is this all completed configuring TUSB422?

please guide me.

sorry for the upset, can you draw a block diagram for what you are trying to do?

initialization of DFP/UFP/DRP can be found on page 13 of datasheet.

Role control is written as 0x05 or0x15 or0x25 if your system is DFP, but will be 0x0A if system is UFP.

hi,

ok now i have solved this issue, is it possible to simulate tusb422 using EV2400 and bq studio?

thanks

no, I don't think so, you need MCU to control it.
