Signal Name
Data Sheet
Address Latch Enable.
External interrupt requests 0 through 4.
External interrupt request 5.
External interrupt requests 6 through 9.
Chip Enable (multiplexed with the PerCS0:3 signals).
Command Latch Enable.
Ready/Busy.
Indicates status of device during program erase or page read.
This signal is wire-or connected from all NAND Flash devices.
Read Enable strobe.
Write Enable strobe.
Clock output.
SCPClkOut, the serial port master clock out, is used to
synchronize all data movement both into and out of the device
through the serial data ports. Normally, data is shifted out on
the rising edge of the clock and shifted in on the negative
edge.
SCPClkOut is also used to shift data into and out of the slave
device. When the SPMODE register is reset, SCPClkOut is
forced to 0.
Data In.
Data is received from the connected slave device and is
captured synchronously with SysClk.
Data output.
Data is sent to the connected slave device synchronously with
SysClk.
Test Clock.
Test Data In.
Test Data Out.
Test Mode Select.
Test Reset.
