BOOL usbh_ohci_hw_irq_en (
  BOOL on
);

The usbh_ohci_hw_irq_en function is used for enabling or disabling the interrupt of the OHCI USB Host controller. The argument on specify if function should do enable or disable interrupts.

The usbh_ohci_hw_irq_en function is part of the RL-USB Host software stack.

You can modify this function to suit different OHCI controller interrupt system. This function will need to be changed if OHCI controller is used on a chip that does not yet have a low level driver provided.

The usbh_ohci_hw_irq_en function returns one of the following manifest constants.

• __TRUE
  Success.
• __FALSE
  Indicates that the enable/disable of interrupts has failed.
