Hi Team

Type C Current mode have 900mA / 1.5A / 3.0A 4 modes. We want change mode on system on S0 . We will use I2C to change 0x29.

Havy any concern on this change? If Type C connect have device on TPS65982, Did we need cheage 0x29 and send 4CC command HRST for restert Type C device?

Hi Kerr,

You do not need to send HRST after changing the device Type-C Current. It would automatically disconnect and reconnect after that register is changed.

Hi Kerr,

No, since the TypeC current field is in register 0x29, the PD controller would not disconnect and reconnect automatically. The changes in this register would take effect next time a connection is made.
