/* The LAN9250 device typically provides interrupts to the MCU through a GPIO
|
||||
* pin. The structure below provides an MCU-independent mechanism for
|
||||
* controlling this LAN9250 GPIO interrupt.
|
||||
*
|
||||
* "When an enabled interrupt occurs, the interrupt pin will remain low until
|
||||
* all flags which are causing the interrupt are cleared or masked off
|
||||
* (enable bit is cleared) by the host controller." However, the interrupt
|
||||
* will behave like a falling edge interrupt because "After an interrupt
|
||||
* occurs, the host controller [clears] the global enable bit for the
|
||||
* interrupt pin before servicing the interrupt. Clearing the enable bit
|
||||
* will cause the interrupt pin to return to the non-asserted state (high).
|
||||
* Doing so will prevent the host controller from missing a falling edge
|
||||
* should another interrupt occur while the immediate interrupt is being
|
||||
* serviced."
