2 Byte vs Word Terminology

Historically, byte is defined as the smallest addressable unit of memory. Hence, technically, the size of a byte is hardware dependent: 16 bits for C28x devices and 8 bits for Arm devices. But nowadays, byte is used as a synonym of 8 bits, since majority of the device architectures are 8 bit addressable. To avoid the confusion, let us use the terminology 8-bit bytes and 16-bit words

Byte and Word Usage in the device feature set Documentation:

From the C28x compiler's perspective, the memory size is always expressed in smallest addressable units, which is 16 bits. This includes the memory length, code/data size provided in the linker cmd files, .map file, and so forth. The standard sizeof() function also returns the size in 16 bits.

• Memory Map Table in device-specific data sheet:
  Table 2-1 Memory Map Table

  Memory	Size	Start Address	End Address
  LS0 RAM	2K × 16	0x0000 8000	0x0000 87FF
  LS1 RAM	2K × 16	0x0000 8800	0x0000 8FFF

• Linker command file:

  RAMLS0     : origin = 0x00008000,  length = 0x0800
  RAMLS1     : origin = 0x00008800,  length = 0x0800
