DEVICE OPERATION
The IS25CD512/010 and IS25LD020 utilize an 8-bit
instruction register. Refer to Table 10 Instruction Set for
details of the Instructions and Instruction Codes. All
instructions, addresses, and data are shifted in with the most
significant bit (MSB) first on Serial Data Input (SI). The input
data on SI is latched on the rising edge of Serial Clock (SCK)
after Chip Enable (CE#) is driven low (V
sequence starts with a one-byte instruction code and is

HOLD OPERATION
HOLD# is used in conjunction with CE# to select the
IS25CD512/010 and IS25LD020. When the devices are
selected and a serial sequence is underway, HOLD# can
be used to pause the serial communication with the
master device without resetting the serial sequence. To

sequence has been shifted in.
The timing for each instruction is illustrated in the following
operational descriptions.
pause, HOLD# is brought low while the SCK signal is low.
To resume serial communication, HOLD# is brought high
while the SCK signal is low (SCK may still toggle during
HOLD). Inputs to SlO will be ignored while SO is in the
high impedance state.
