INSTRUCTIONAL NOTES |
To set ports interrupts to unique IRQs, refer to the appropriate 'Port (X) Discrete Serial Interrupt Selection' table(s). For multiple ports assigned to a single, shared interrupt, assign the desired ports to shared IRQ and then assign an IRQ using the 'Shared Serial Port Interrupt Selection' table. |
