1.1.2

SOFTWARE DEVICE RESET

The 25CS160 includes a Software Device Reset

(SRST) instruction that gives the user the opportunity to

reset the device to its power-on default behavior

(Section 1.2 “Device Default State”) without the need

to power cycle the device. To execute this Reset, the

CS pin must first be driven low to select the device, and

then a 7Ch opcode is clocked in on the SI pin.

Then the CS pin can be driven high, and the Reset

mechanism will engage. The Reset will have internally

completed by the time the minimum TCSD time is

satisfied.

Note:

The SRST instruction cannot interrupt the

device while it is in a Busy state

(Section 6.1.4 “Ready/BUSY STATUS

LATCH”).
