SPI READ/WRITE DATA FORMATS
The read/write formats of the SPI port are designed to be byte-
oriented. This allows for easy programming of common
microcontroller chips to fit into a byte-oriented format; 0s are
appended to the data fields to extend the data-word to the next
multiple of eight bits. For example, 22-bit words written to the
SPI parameter RAM are appended with two leading zeros to
reach 24 bits (three bytes), and 35-bit words written to the
program RAM are appended with five zeros to reach 40 bits
(five bytes). These zero-extended data fields are appended to
a 2-byte field consisting of a read/write bit and a 10-bit address.
The SPI port knows how many data bytes to expect based on
the address that is received in the first two bytes.
The total number of bytes for a single-location SPI write command
can vary from four bytes (for a control register write), to seven
bytes (for a program RAM write). Block writes may be used to
fill contiguous locations in program RAM or parameter RAM.
