Hello Champs,
There is below description for PHY Reset signal for ESC in F2838x TRM:
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
31.1.6.2.2 PHY Reset Signal
The PHY reset signal is generated out of the ESC module. If it is required to release both, the PHY and ESC module synchronous out of reset, this signal can be used. Since there are no pull devices active on the MCU during and after reset, a pull down resistor must be added on this signal on the board level.
In some case, PHYs may be released from reset after releasing the ESC module. To generate a delay, the pin for nPHY_RESET can be used as an I/O and shall be switched later to the alternate output function.
-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Would you please help what condition will cause the PHY reset signal to always be low after power up? Thanks!
Best Regards,
Linda
