• Description: Ibm Processor For Network Resources
• Manufacturer: ETC-unknow

Preliminary
21.1: Instruction Format
The processor’s JTAG logic supports 32-bit instructions in one of two formats: the first format uses opcodes
compliant with the IEEE standard; the other supports opcodes as defined by the Walnut chip that are compat-
ible but not compliant with the IEEE standard. As an instruction is scanned in, status for the previous instruc-
tion is presented on TDO.
