| 5 | /* The _WORD_ACCESS option is an only platform dependent option. It defines | |

| 8 | / 0: Byte-by-byte access. Always compatible with all platforms. | |
| 9 | / 1: Word access. Do not choose this unless under both the following conditions. | |

| 11 | / * Address misaligned memory access is always allowed to ALL instructions. | |
| 12 | / * Byte order on the memory is little-endian. | |
| 13 | / | |
| 14 | / If it is the case, _WORD_ACCESS can also be set to 1 to reduce code size. | |
