Chapter 6
Instruction Set
Chapter 6 lists the instructions that can be sent to the L64381 on the
Processor Interface. Most instructions read and write the L64381 internal
registers. The L64381 also provides special instructions that facilitate
transfers of statistical information and that control and observe registers
and FIFOs. Refer to Chapter 2, “Registers,” for more details on the reg-
ister descriptions.
This chapter contains the following sections:
Section 6.1, “Instruction Set Summary”
Section 6.2, “Accessing the Data FIFO”
Section 6.3, “Accessing the Statistics Counters”
6.1
Instruction Set
Summary
Table 6.1 lists all of the L64381 instructions. The instructions are ordered
according to instruction type: read/write register, read and autoincrement,
and burst read. Certain instructions operate only in specific Diagnostic
Modes. Table 6.1 also specifies the particular operating mode(s).
