Hold Operation
between host and CAT25010/20/40. To pause, HOLD must
be taken low while SCK is low (Figure 11). During the hold
condition the device must remain selected (CS low). During
the pause, the data output pin (SO) is tri−stated (high
impedance) and SI transitions are ignored. To resume
communication, HOLD must be taken high while SCK is low.
Design Considerations
Reset (POR) circuitry which protects the internal logic
against powering up in the wrong state. The device will
power up into Standby mode after V
trigger level and will power down into Reset mode when

byte/page write or status register write, the device goes into
a write disable mode. The CS input must be set high after the
proper number of clock cycles to start the internal write
cycle. Access to the memory array during an internal write
cycle is ignored and programming is continued. Any invalid
op−code will be ignored and the serial output pin (SO) will
remain in the high impedance state.
