This appendix serves as a reference regarding notational conventions used throughout the specification.
F.1
The general representation for numbers is as follows:
The suffix is often dropped for clarity when the context makes the intended radix obvious. Note that this suffix
convention requires that letters [ABCDEF] used in hex numbers always be capitalized.
F.2
By historical convention, digital voice data represented in octet samples are transmitted serially starting at the
leftmost bit (i.e., MSB = bit 1) and proceeding down to the rightmost bit of the sample (i.e., LSB = bit 8).
On the other hand, data organized in n-bit words is transmitted serially starting with the rightmost bit (i.e., LSB = bit
0) and proceeding along to the left most bit (i.e., MSB = bit n-1).
CX28500 is designed to support the data transmission convention. That is, on the receive side, serial data is
placed in the LSB of a word first up to the MSB. On the transmit side, the LSB (i.e., bit 0) is transmitted first, then on
up to the MSB.
