programmable interrupt controller (PIC)
chip set through which the
microprocessor can be notied of time
critical events. Some IRQ lines are
reserved for standard devices such as the
keyboard, diskette drive, and the system
clock. A software interrupt is a
programmatic mechanism to allow an
application to get the attention of the
processor.
CIM_MemoryMappedIO
The CIM_MemoryMappedIO class described in properties Table below addresses both memory and port I/O resources for personal
computer architecture memory mapped I/O.
Table 50. CIM_MemoryMappedIO Properties
Class Name:
CIM_MemoryMappedIO
Parent Class:
CIM_SystemResource
Property Description Data Type
CSCreationClassName See Common Properties of Classes string
CSName See Common Properties of Classes string
CreationClassName See Common Properties of Classes string
StartingAddress Identies the starting address of memory
mapped I/O.
uint64
EndingAddress Identies the ending address of memory
mapped I/O.
uint64
MappedResource Indicates the type of memory mapped I/O.
MappedResource denes if memory or
I/O is mapped, and for I/O, if the mapping
is to a memory or a port space. Memory
mapped I/O values are as follows:
1- Other
2- Mapped memory
3 - I/O mapped to memory space
4- I/O mapped to port space
uint16
