Abbreviation
IRQ[7:1]
External interrupt sources.
Table 2-7. Queued Serial Peripheral Interface (QSPI) Signals
Abbreviation
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.
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.
QSPI_CLK
Provides the serial clock from the QSPI. The polarity and phase of
QSPI_CLK are programmable.
QSPI_CS[3:0] QSPI peripheral chip selects that can be programmed to be active
high or low.
