QSPI Synchronous
Serial Output
QSPI_DOUT Provides the serial data from the QSPI and can be programmed to be
driven on the rising or falling edge of QSPI_CLK.
O
QSPI Synchronous
Serial Data Input
QSPI_DIN Provides the serial data to the QSPI and can be programmed to be
sampled on the rising or falling edge of QSPI_CLK.
I
QSPI Serial Clock QSPI_CLK Provides the serial clock from the QSPI. The polarity and phase of
QSPI_CLK are programmable.
O
Synchronous Peripheral
Chip Selects
QSPI_CS[3:0] QSPI peripheral chip select; can be programmed to be active high or
low.

Signal Name Abbreviation Function I/O
Serial Clock SCL Open-drain clock signal for the for the I
2
C interface. When the bus is
In master mode, this clock is driven by the I
2
C module; when the bus
is in slave mode, this clock becomes the clock input.
I/O
Serial Data SDA Open-drain signal that serves as the data input/output for the I
2
C
interface.
