Function Documentation

void USBAm43Gs70PhyEnableWakeUp ( uint32_t  instNum)

This API enables PHy based wake up for USB module. When enabled PHy clock is kept on during Power down and this feature can be used for System bring up.

Parameters
instNuminstance number of the controller instance whose phy wake feature needs to be enabled.
uint32_t USBAm43Gs70PhyGetWakeUpStatus ( uint32_t  instNum)

This function returns the wakeup status of the USB Phy.

Parameters
instNuminstance number of the controller instance whose phy wake feature needs to be probed.
Return values
Value1or 0 1 if wakeup is enabled and 0 other wise.
void USBAm43Gs70PhyInvPolarity ( uint32_t  instNum)

This API Inverts the DP/DM polarity coopared with the normal polarity of the port.

Parameters
instNuminstance number of the controller instance whose Phy polarity needs to be inverted.
void USBAm43Gs70PhyOn ( uint32_t  instNum)

This API turns on the AM43xx USB GS70 phy. VBUS detect, and session comparators are turned on.

Parameters
instNuminstance number of the controller instance whose Phy is to be turned on.
