Queued Serial Peripheral Interface (QSPI) Signals
19.15 Queued Serial Peripheral Interface (QSPI)
This section describes signals used by the queued serial peripheral interface (QSPI)
module. Four QSPI chip selects, QSPI_CS[3:0], are multiplexed with the physical layer
interface pins and GPIO port A. QSPI_CS0 is always available. QSPI_CS3 is multiplexed
with DOUT3 and PA7.
19.15.1 QSPI Synchronous Serial Data Output
The QSPI synchronous serial data output (QSPI_Dout) can be programmed to be driven on
the rising or falling edge of SCK. Each byte is sent msb first.
WSEL configuration input is sampled on the rising edge of Reset Output (RSTO).
19.15.2 QSPI Synchronous Serial Data Input (QSPI_Din)
The QSPI synchronous serial data input (QSPI_Din) can be programmed to be sampled on
the rising or falling edge of QSPI_CLK. Each byte is written to RAM lsb first.
19.15.3 QSPI Serial Clock (QSPI_CLK/BUSW1)
The QSPI serial clock (QSPI_CLK/BUSW1) provides the serial clock from the QSPI. The
polarity and phase of QSPI_CLK are programmable. The output frequency is programmed
according to the following formula, in which n can be any value between 1 and 255:
At reset, QSPI_CLK/BUSW1 is used to configure the width of memory connected to CS0.
BUSW1 configuration input is sampled on the rising edge of Reset Output (RSTO).
19.15.4 Synchronous Peripheral Chip Select 0
The synchronous peripheral chip select 0 (QSPI_CS0) output provides a QSPI peripheral
chip select that can be programmed to be active high or low. During reset, this pin is used
to configure the width of memory connected to CS0.
BUSW0 configuration input is sampled on the rising edge of Reset Output (RSTO).
