Bit ordering in PBL

Question asked by Tom Hohenstein on Aug 2, 2018
Latest reply on Aug 3, 2018 by Tom Hohenstein

In section 26.4.3 of the LS1046A reference manual (Rev. 1) the first byte of the PBL preamble is defined as follows:


Bit 0Bit 1Bit 2Bit 3Bit 4Bit 5Bit 6Bit 7


Under the assumption that Bit 0 is the least significant bit, I would expect the first preamble byte to be 0x55. But when I dump the contents of the SD card I'm using I see that the first byte of the preamble is 0xAA instead.


So my question is:

Are the column labels of the PBL data structure in the reference manual in the wrong order or am I missing something else here?


Any help would be appreciated!
