DESCRIPTION
25 IRQB
In
3.3
Interrupt request port B, Boot Mode Select. One of 4 IRQ pins. Connects to logic high (3.3V) or to
ground and High/Low logic status establishes boot mode selection upon de-assertion of reset
(nRESET) cycle.
26 IRQC
In
3.3
Interrupt request port C, Boot Mode Select. One of 4 IRQ pins. Connects to logic high (3.3V) or to
ground and High/Low logic status establishes boot mode selection upon de-assertion of reset
(nRESET) cycle.
27 IRQD
In
3.3
Interrupt request port D, Boot Mode Select. One of 4 IRQ pins. Connects to logic high (3.3V) or to
ground and High/Low logic status establishes boot mode selection upon de-assertion of reset
(nRESET) cycle.
