Interrupts
A single, low level error condition can generate numerous false interrupts. For
example, a LOS condition results in almost all other interrupts being set, even
though only the LOS condition needs to be addressed by software. To help
simplify the software interrupt routines, the CX29600 automatically supresses
higher-level interrupt when the errors shown in
LOS
