Sequence Length Specification
These bits specify a sequence length when this
module in master mode performs sequential
operations. This module in master mode changes
command registers 0 to 3 (SPCMD0 to SPCMD3) to
be referenced and the order in which they are
referenced according to the sequence length that is
set in the SPSLN1 and SPSLN0 bits.
The relationship among the setting of bits SPSLN1
and SPSLN0, sequence length, and SPCMD0 to
SPCMD3 referenced by this module is shown below.
In slave mode, SPCMD0 is always referenced.
