Note:
SPI Protocols
The N25Q128 memory can work with 3 different Serial protocols:
It is possible to choose among the three protocols by means of user volatile or non-volatile
configuration bits.It's not possible to mix Extended SPI, DIO-SPI, and QIO-SPI protocols.
The device can operate in XIP mode in all 3 protocols.
Extended SPI protocol
This is an extension of the standard (legacy) SPI protocol. Instructions are transmitted on a
single data line (DQ0), while addresses and data are transmitted by one, two or four data
lines (DQ0, DQ1, W/VPP(DQ2) and HOLD / (DQ3) according to the instruction.
When used in the Extended SPI protocol, these devices can be driven by a micro controller
in either of the two following modes:
Please refer to the SPI modes for a detailed description of these two modes
Dual I/O SPI (DIO-SPI) protocol
Dual I/O SPI (DIO-SPI) protocol: instructions, addresses and I/O data are always
transmitted on two data lines (DQ0 and DQ1).
Also when in DIO-SPI mode, the device can be driven by a micro controller in either of the
two following modes:
Please refer to the SPI modes for a detailed description of these two modes.
Extended SPI protocol Dual I/O instructions allow only address and data to be transmitted
over two data lines. However, DIO-SPI allows instructions, addresses, and data to be
transmitted on two data lines.
This mode can be set using two ways
Extended SPI protocol.
Dual I/O SPI (DIO-SPI) protocol.
Quad I/O SPI (QIO-SPI) protocol.
CPOL=0, CPHA=0
CPOL=1, CPHA=1
CPOL= 0, CPHA= 0
CPOL= 1, CPHA= 1
Volatile: by setting bit 6 of the VECR to 0. The device enters DIO-SPI protocol
immediately after the Write Enhanced Volatile Configuration Register sequence
completes. The device returns to the default working mode (defined by NVCR) on
power on.
Default/ Non-Volatile: This is default mode on power-up. By setting bit 2 of the NVCR
to 0. The device enters DIO-SPI protocol on the subsequent power-on. After all
subsequent power-on sequences, the device still starts in DIO-SPI protocol unless bit 2
of NVCR is set to 1 (default value, corresponding to Extended SPI protocol) or bit 3 of
NVCR is set to 0 (corresponding to QIO-SPI protocol).
