Application must implement IRQ Handler and invoke `tud_irq_handler(rhport)`. This is due to: + + - IRQ Handler name can be different across system depending on the startup + - Some OS need to execute enterISR()/exitISR() to work properly, also tracing tool may need to insert trace ISR enter/exit to record usb event + - Give application full control of IRQ handler, can be useful e.g signaling there is new usb event without constant polling + +### MCU + +- All default IRQ Handler is renamed to `dcd_irq_handler()` ## 0.6.0 - 2019.03.30 |
