MEMORY MAP AND REGISTERS
MEMORY MAP
Table 16 provides a list of the memory registers that can be
read from or written to by the user. See the SPI Communication
Protocol section for the proper input sequence to read from or
write to a specific memory register. Each memory register has
eight bits of data; however, when a read request is performed,
the data always returns as a 16-bit message. This is accomplished
by appending the data from the next sequential register to the
memory address that was specified.

Data is transmitted MSB first. For proper acquisition of data from
the memory register, make the read request to the even-numbered
register address only; for example, to read the LOCSTx registers,
address Register 0x04, but not Register 0x05. For a description of
each memory register listed in Table 16, see the Memory Register
Definitions section.
