10 / 23 page PRELIMINARY FM25V40 Document Number: 001-87288 Rev. *A Page 10 of 23 HOLD Pin Operation The HOLD pin can be used to interrupt a serial operation without aborting it. If the bus master pulls the HOLD pin LOW while SCK is LOW, the current operation will pause. Taking the HOLD pin HIGH while SCK is LOW will resume an operation. The transitions of HOLD must occur while SCK is LOW, but the SCK and CS pin can toggle during a hold state. Figure 13.
