Chip signal name Module signal
Name
Description I/O
second device in a dual-die package
flash A or the second of the two flash
devices that share IOFA.
QSPI0B_SS0_B PCSFB1 Peripheral Chip Select Flash B1. This
signal is the chip select for the serial
flash device B1. B1 represents the
first device in a dual-die package flash
B or the first of the two flash devices
that share IOFB.
O
QSPI0A_SCLK SCKFA Serial Clock Flash A. This signal is the
serial clock output to the serial flash
device A.
O
QSPI0B_SCLK SCKFB Serial Clock Flash B. This signal is the
serial clock output to the serial flash
device B.

IOFA[7:0] Serial I/O Flash A. These signals are
the data I/O lines to/from the serial
flash device A. Note that the signal
pins of the serial flash device may
change their function according to the
SFM Command executed, leaving
them as control inputs when Single
and Dual Instructions are executed.
The module supports driving these
inputs to dedicated values.

IOFB[3:0] Serial I/O Flash B. These signals are
the data I/O lines to/from the serial
flash device B. Note that the signal
pins of the serial flash device may
change their function according to the
SFM Command executed, leaving
them as control inputs when Single
and Dual Instructions are executed.
The module supports driving these
inputs to dedicated values.
I/O
QSPI0A_DQS DQSFA Data Strobe signal Flash A. Data
strobe signal for port A. Some flash
vendors provide the DQS signal to
which the read data is aligned in DDR
mode.
