EVIOMK[0:4][0:3]
Interrupt Output Mask Registers.
There are 20 of
these registers. The first digit in the register names
indicates which output signal the register applies to,
the second digit indicates which group of input signals
the register applies to. Each 1 in these registers
enables the corresponding signal to contribute to that
output of the Event Router block. These registers can
be written during system initialization, but changing
their values dynamically should be done using the
Interrupt Output Mask Set and Clear Registers.

EVIOMC[0:4][0:3]
Interrupt Output Mask Clear Registers.
The first
digit in the names of these 20 registers indicates
which output signal the register applies to, the second
digit indicates which group of input signals the
register applies to. Writing 1s to these registers clears
the corresponding bits of the Interrupt Output Mask
Registers, thus disabling the corresponding signal
from contributing to that output of the Event Router
block.

Interrupt Output Mask Set Registers.
The first digit
in the names of these 20 registers indicates which
output signal the register applies to, the second digit
indicates which group of input signals the register
applies to. Writing 1s to these registers set the
corresponding bits of the Interrupt Output Mask
Registers, thus enabling the corresponding signal to
contribute to that output of the Event Router block.

EVIOP[0:4][0:3]
Interrupt Output Pending Registers.
The first digit
in the names of these 20 registers indicates which
output signal the register applies to, the second digit
indicates which group of input signals the register
applies to. Each 1 in these read-only registers
indicates that the corresponding signal is causing that
output to be asserted.

EVOUT
Event Router Output Register.
Each 1 in bits 4:0 of
this read-only register indicates that the Event Router
is asserting its corresponding output.

EVFEATURES
Features Register.
This constant read-only register
allows general-purpose software to determine how
many inputs and outputs the Event Router includes.
