FUNCTION: User Interrupt
DESCRIPTION:
The UI command causes an interrupt on the selected IRQ line. There are 16 user interrupts where
UI n, n = 0 through 15. Prior to using the UI command, one IRQ line must be enabled on the
controller and the data 2 and 4 written to the control register at address N + 1. An interrupt
service routine must also be incorporated in your host program. The interrupt condition can
be read by writing a 6 to address N + 1 and then reading address N + 1. Refer to the user
manual for additional information.
