Data and command sequences are serially written to or
serially read from the device through the I/O pin.

PIN DESCRIPTIONS
Chip Enable (CE)
The Chip Enable input must be LOW to enable all read/
write operations. When CE is HIGH, the chip is dese-
lected, the I/O pin is in the high impedance state, and
unless a nonvolatile write operation is underway, the
device is in the standby power mode.
Output Enable (OE)
The Output Enable input must be LOW to enable the out-
put buffer and to read data from the device on the I/O line.
Write Enable (WE)
The Write Enable input must be LOW to write either data
or command sequences to the device.
Data In/Data Out (I/O)
Write Protect (WP)
The Write Protect input controls the Hardware Write Pro-
tect feature. When WP is LOW and the nonvoltaile bit
WPEN is “1”, nonvolatile writes of the X84160/640/128
control register is disabled, but the part otherwise func-
tions normally. When WP is held HIGH, all functions,
including nonvolatile write operate normally. WP going
LOW while CS is still LOW will interrupt a write to the
X84160/640/128 control register. If the internal Write
cycle has already been initiated, WP going LOW will
have no effect on write.
The WP pin function is blocked when the WPEN bit in the
control register is “0”. This allows the user to install the
X84160/640/128 in a system with WP pin grounded and
still be able to write to the control register. The WP pin
functions will be enabled when the WPEN bit is set “1”.
