KFTIA and KFTHA support the PCI bus, XMI bus, and the Futurebus+,
depending on the system in which they are used. The chapter describes
the transaction types on the TLSB interface and the hose interface. It pre-
sents a brief survey of the integrated I/O port (KFTIA). The survey focuses
mainly on the integrated I/O section of the module, which provides two PCI
buses that support ports for PCI devices such as Ethernet, SCSI, FDDI,
and NVRAM. The chapter also discusses the types of errors that affect the
hoses and how the I/O port handles errors.
Chapter 7, System Registers, describes in detail the functions of the sys-
tem registers, which include the TLSB bus registers, CPU module regis-
ters, memory module registers, and I/O port registers. For KFTIA regis-
ters and device registers supported by the integrated I/O port, the reader is
referred to source material. This chapter is the only place where functions
of all registers are discussed fully at the bit level.
Chapter 8, Interrupts, gives an overview of various interrupts within the
system. It discusses vectored and nonvectored interrupts, interrupt rules,
mechanisms, and service.
Results of operations termed Unpredictable may vary from moment to
moment, implementation to implementation, and instruction to instruction
within implementations. Software must never use Unpredictable results.
Operations termed Undefined may vary from moment to moment, imple-
mentation to implementation, and instruction to instruction within imple-
mentations. Undefined operations may halt the processor or cause it to
lose information. However, they do not cause the processor to hang; that
is, reach a state from which there is no transition to a normal state of in-
struction execution. Nonprivileged software cannot invoke Undefined op-
erations.
