Definitions required to support the use of LEA.
| #define MSP_LEA_RANGE | ( | x | ) |
Check that the address is aligned correctly.
| #define MSP_USE_LEA 1 |
Enable the LEA accelerator for DSPLib functions. The default is to use LEA when available, to disable LEA define MSP_DISABLE_LEA in the compiler settings.
It is always recommended to use LEA for lowest power and best performance. Disabling LEA is only intended to be used for benchmarking LEA performance against the CPU and hardware multiplier or by users who would like to dedicate the LEA peripheral to a specific function and run the remainder on the CPU.
