2.6.4.1
The section declaration family of pragmas changes the section into which
MPLAB C17 will allocate data of the associated type. Optionally, the section may be
allocated at an absolute address.
A section declaration with no name resets the allocation of data of the associated type
to the default section for the current module.
A data section qualified as
Similarly, a data section qualified as
linker.
Specifying a section name which has been previously declared causes MPLAB C17 to
resume allocating data of the associated type into the specified section. The section
qualifiers must match the previous declaration.
For
and a bank number may be optionally specified instead of an absolute address. This
is functionally equivalent to specifying a
