The bus signals required are a clock input (SCK) plus sep- arate data in (SI) and data out (SO) lines. Access to the device is controlled through a Chip Select (CS) input. Communication to the device can be paused via the hold pin (HOLD). While the device is paused, transi- tions on its inputs will be ignored, with the exception of Chip Select, allowing the host to service higher priority interrupts. The 25XX320A is available in standard packages including 8-lead PDIP and SOIC, and advanced packaging including 8-lead MSOP, TSSOP and 2x3 TDFN.
