-// So, on this image, in order to get an interrupt from
-// e.g. pressing BUTTON_0:
-// 1) Steps which are external to the delivery coreplex:
-// a) The corresponding GPIO pin must be configured as in input
-// b) The "interrupt on fall" bit must be set for the GPIO pin
-// 2) Steps which would also need to be performed for the delivery coreplex:
-// a) The corresponding global interrupt, priority, and threshold must be configured in the PLIC.
-// b) The external interrupt bit must be enabled in MSTATUS
-// c) Interrupts must be enabled globally in the core.
-
-// Any of the above GPIO pins can be used as global interrupt
-// sources by adding their offset to the INT_GPIO_BASE.
