EnableEP
void(*void USBD_HW_API::EnableEP)(USBD_HANDLE_T hUsb, uint32_t EPNum)
Function to enable selected USB endpoint.
This function enables interrupts on selected endpoint.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number as per USB specification. ie. An EP1_IN is represented by 0x81
number.
Returns:
Nothing.
This function enables interrupts on selected endpoint.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number corresponding to the event as per USB specification. ie. An EP1_IN is
represented by 0x81 number. For device events set this param to 0x0.
3. event = Type of endpoint event. See USBD_EVENT_T for more details.
4. enable = 1 - enable event, 0 - disable event.
Returns:
Returns ErrorCode_t type to indicate success or error condition.
Return values:
1. LPC_OK(0) = - On success
2. ERR_USBD_INVALID_REQ(0x00040001) = - Invalid event type.

Function to disable selected USB endpoint.
This function disables interrupts on selected endpoint.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number as per USB specification. ie. An EP1_IN is represented by 0x81
number.
Returns:
Nothing.

void(*void USBD_HW_API::ResetEP)(USBD_HANDLE_T hUsb, uint32_t EPNum)
Function to reset selected USB endpoint.
This function flushes the endpoint buffers and resets data toggle logic.
Parameters:
1. hUsb = Handle to the USB device stack.
2. EPNum = Endpoint number as per USB specification. ie. An EP1_IN is represented by 0x81
number.
Returns:
Nothing.
