SPI modes (0,0 & 1,1).
SCK:
Serial Clock
SCK is the serial clock pin. This pin is used to synchronize
the communication between the microcontroller and the
25C11/03/05/09/17. Opcodes, byte addresses, or data
present on the SI pin are latched on the rising edge of the
SCK. Data on the SO pin is updated on the falling edge of
the SCK for SPI modes (0,0 & 1,1).
CS
:
Chip Select
CS
is the Chip select pin.
CS
low enables the CAT25C11/
03/05/09/17 and
CS
high disables the CAT25C11/03/05/
09/17.
CS
high takes the SO output pin to high impedance

WRITE PROTECT ENABLE OPERATION
and forces the devices into a Standby Mode (unless an
internal write operation is underway) The CAT25C11/03/
05/09/17 draws ZERO current in the Standby mode. A
high to low transition on
CS
is required prior to any
sequence being initiated. A low to high transition on
CS
after a valid write sequence is what initiates an internal
write cycle.
WP
:
Write Protect
WP
is the Write Protect pin. The Write Protect pin will allow
normal read/write operations when held high. When
WP
is
tied low and the WPEN bit in the status register is set to "1",
all write operations to the status register are inhibited.
WP
going low while
CS
is still low will interrupt a write to the
status register. If the internal write cycle as already been
initiated,
WP
going low will have no effect on any write
