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 com-
plete conversion. Writing a value to DTL[7:0] in SPCR1 specifies a delay period. The
DT bit in each command RAM byte determines whether the standard delay period (DT
= 0) or the user-specified delay period (DT = 1) is used. The following expression is
used to calculate the delay:
where DTL equals {1, 2, 3,..., 255}.
A zero value for DTL[7:0] causes a delay-after-transfer value of 8192/f
Adequate delay between transfers must be specified for long data streams because
the QSPI requires time to load a transmit RAM entry for transfer. Receiving devices
need at least the standard delay between successive transfers. If the system clock is
operating at a slower rate, the delay between transfers must be increased proportion-
ately.
