3.10 INTERRUPT HANDLING
The INT_CH[7:0] bits (INTCH, 09H) should be read to identify which chan-
nel(s) generate the interrupt.
Status Register (INTS0, 3AH...) or (INTS1, 3BH...). Every kind of interrupt
can be enabled/disabled individually by the corresponding bit in the register
(INTENC0, 33H...) or (INTENC1, 34H...). Some event is reflected by the
corresponding bit in the Status Register (STAT0, 36H...) or (STAT1,
37H...), and the Interrupt Trigger Edge Selection Register can be used to
determine how the Status Register sets the Interrupt Status Register.
read, the corresponding bit indicating which channel generates the inter-
rupt in the INTCH register (09H) will be reset. Only when all the pending
interrupt is acknowledged through reading the Interrupt Status Registers
of all the channels (INTS0, 3AH...) or (INTS1, 3BH...) will all the bits in the
INTCH register (09H) be reset and the INT pin become inactive.

FUNCTIONAL DESCRIPTION
IDT82P5088
Arbitrary Waveform Generator Overflow
Synchronization Status of PRBS/QRSS
