Code and data sections

Because the eTPU has two memory spaces, it is not enough to specify an address for a

section. You must also specify a memory space. Specifying a memory space is done in the

LCF using the segments access permission flags.

A segment that has the X (executable) flag will be loaded to the instruction memory.

A segment that does not have the X (executable) flag will be loaded to the data memory.
