3.8 COS Latch Register
When COS occurs, the COS Latch register will also latch the DI
data. Once the user clear the interrupt request, the COS Latch
register will be cleared automatically. The COS function releases
the CPU from the burden of polling all of the input channels, and
enables the computer to handle higher I/O performance.
