8.3
All interrupt control registers are organized identically. The lower 8 bits of an interrupt
control register contain the complete interrupt status information of the associated
source, which is required during one round of prioritization, the upper 8 bits of the
respective register are reserved. All interrupt control registers are bit-addressable and all
bits can be read or written via software. This allows each interrupt source to be
programmed or modified with just one instruction. When accessing interrupt control
registers through instructions which operate on word data types, their upper 8 bits
(15...8) will return zeros, when read, and will discard written data.
The layout of the Interrupt Control registers shown below applies to each xxIC register,
where xx stands for the mnemonic for the respective source.
