8.3.1 Interrupt OR Mask Register (INTC_ORMR)
The INTC_ORMR provides a mechanism to enable/disable the combined interrupt requests associated
with SCI3 and the FEC.
The SCI3 and FEC modules have interrupt sources that are the logical summation (the boolean OR) of
multiple interrupt requests. These two interrupt requests can be configured to enable the OR’d version of
the interrupt request or the separate individual requests.
The reset state of the INTC_ORMR disables (masks) the OR’d interrupt requests. If the OR’d version of
the SCI3 or FEC interrupt sources is used, they first must be properly enabled (unmasked) by writing to
this register.
