Disabling this option saves some code size.

This configuration option enables optimizations to speedup (about 3 ~ 4 times) the ECP
fixed point multiplication using pre-computed tables in the flash memory.
Disabling this configuration option saves flash footprint (about 29KB if all Elliptic Curve selected)
in the application binary.
