WebIf you don’t want to use interrupts, set phydev->irq to PHY_POLL. phy_start () enables the PHY interrupts (if applicable) and starts the phylib state machine. When you want to disconnect from the network (even if just briefly), you call phy_stop (phydev). This function also stops the phylib state machine and disables PHY interrupts. WebNov 27, 2024 · In the I2C protocol there is a way for slave devices to force the master to wait and this is called clock stretching. In master mode, the PIC32 can detect and handle this automatically and we don't need to worry about it. If we want to implement clock stretching, we can do so by setting the STR_EN bit in I2CxCON.
