Queued Serial Multi-Channel Module
15.6.5.3
The DSCK bit in each command RAM byte inserts either a standard (DSCK = 0) or user-specified (DSCK
= 1) delay from chip-select assertion until the leading edge of the serial clock. The DSCKL field in SPCR1
determines the length of the user-defined delay before the assertion of SCK. The following expression
determines the actual delay before SCK when DSCKL is in the range of 1–127:
When DSCK equals zero, DSCKL is not used. Instead, the PCS valid-to-SCK transition is one-half the
SCK period.
15.6.5.4
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. Writing a value to
the DTL field in SPCR1 specifies a delay period. The DT bit in each command RAM byte 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:
A zero value for DTL causes a delay-after-transfer value of 8192 ÷ IMB3 clock frequency (204.8 µs with
a 40-MHz IMB3 clock).
If DT is zero in a command RAM byte, a standard delay is inserted.

Table 15-21. Example SCK Frequencies with a 40-MHz IMB3 Clock (continued)
where DTL is in the range from one to 255.
A zero value for DSCKL causes a delay of 128 IMB3 clocks, which equals
3.2 µs for a 40-MHz IMB3 clock. Because of design limits, a DSCKL value
of one defaults to the same timing as a value of two.
