14.4.3 Transfer Delays
The QSPI supports programmable delays for the QSPI_CS signals before and after a
transfer. The time between QSPI_CS assertion and the leading QSPI_CLK edge, and the
time between the end of one transfer and the beginning of the next, are both independently
programmable.
The chip select to clock delay enable (DSCK) bit in command RAM, QCR[DSCK], enables
the programmable delay period from QSPI_CS assertion until the leading edge of
QSPI_CLK. QDLYR[QCD] determines the period of delay before the leading edge of
QSPI_CLK. The following expression determines the actual delay before the QSPI_CLK
leading edge:
QCD has a range of 1–127.
When QCD or DSCK equals zero, the standard delay of one-half the QSPI_CLK period is
used.
The delay after transmit enable (DT) bit in command RAM enables the programmable
delay period from the negation of the QSPI_CS signals until the start of the next transfer.
The delay after transfer can be used to provide a peripheral deselect interval. A delay can
also be inserted between consecutive transfers to allow serial A/D converters to complete
conversion. There are two transfer delay options: the user can choose to delay a standard
period after serial transfer is complete or can specify a delay period. Writing a value to
QDLYR[DTL] specifies a delay period. The DT bit in command RAM determines whether
the standard delay period (DT = 0) or the specified delay period (DT = 1) is used. The
following expression is used to calculate the delay:
where QDLYR[DTL] has a range of 1–255.
