CY325 ETC, CY325 Datasheet - Page 54

• Manufacturer Part Number: CY325
• Description: Stepper System Controller
• Manufacturer: ETC

Each parameter has been assigned a potential range of 8 addresses, to make the address
decoding easier. Only the addresses shown are actually used to read digit values. The CY545
will not generate the unused address values.
Any parameter that will not be read from switches does not require the 74LS156 or switches for
that parameter. Any group of parameters that will not be read from switches does not require
the 74LS138 decoder either.
