Note: The IIC module will look at a new transaction on the I
Therefore, software must make sure that “interrupt clear” is the last transaction that is sent to the IIC module before starting
a new transaction.

Description
Ignore upon read. Write as zeroes.
Interrupt status register. It reports any pending interrupts:
Ignore upon read. Write as zeroes.
Interrupt enable register
Ignore upon read. Write as zeroes.
Interrupt clear register.
Ignore upon read. Write as zeroes.
Interrupt set register. Allows software to set interrupts.
Module returns DEADABBA on all reads except for reads of the
powerdown bit. Module generates ERR ACK on all writes except for
writes to the powerdown bit.
Ignore upon read. Write as zeroes.
Unique 16-bit code. Module ID

Aperture size = 4 kB*(bit_value+1), so 0 means 4 kB (the default).
1 = Interrupt i pending.
0 = Interrupt i not pending.
1 = Interrupt i is enabled.
0 = Interrupt is disabled.
1 = Interrupt is cleared.
0 = Interrupt is not cleared.
1 = Interrupt is set
0 = Interrupt is not set.
0 = Normal operation of peripheral. This is the reset value.
1 = Module is powerdown and module clock can be removed.
2
C bus as soon as the previous interrupt has been cleared.
