Canonlake cs3 sd card a 375 driver8/29/2023 When the driver finishes processing the interrupt, it informs the bus driver by an explicit call to an interrupt acknowledgment routine supplied with the SD bus interface. The driver can return from the callback routine and complete interrupt processing in its own context. The device driver does not have to complete interrupt processing in the context of the interrupt notification callback routine. The SD bus driver detects and intercepts hardware interrupts, and then reports them to the device driver by means of the interrupt notification callback routine PSDBUS_CALLBACK_ROUTINE, as explained in sections Secure Digital (SD) Driver Stack and Opening and Initializing an SD Bus Interface. Secure Digital (SD) card drivers do not have interrupt service routines (ISRs) and they do not acquire interrupt request (IRQ) resources.
