LSB vs. MSB on xCORE-200 chip

Post by tbadams45 »

I'm designing a PCB that uses the xCORE-200 series chip in tandem with a partner of mine (datasheet: https://www.xmos.com/download/private/X ... (1.11).pdf). The xCORE-200 offers several multi-bit ports, and I'm looking for confirmation on which bits on these ports are the most/least significant.

For example, in the image below, is X0D02 the LSB of the 8-bit port A, or is X0D09?

Thanks for the help.

Yes.

X0D02 = 8A0 = 8 bit wide port and is Bit 0. LSB.

X0D09 = 8A7 = 8 bit wide port and is Bit 7. MSB.
