I was hoping someone could explain the effect of the SAI MSB First (MF) field on the receipt of data via I2S.
In this case, does MSB still stand for most significant byte (and not most significant bit)?
My interpretation is the following:
MSB First (MF) specifies if the first byte received per word is the most significant or least significant.
1111 0000 0000 1111 is shifted out, from left to right
With the MSB First (MF) set to 1 (selecting MSB):
The sample value is 0xF00F
the receive buffer (in our little-endian system) reads:
Base Address: 0x0F
Base Address + 1: 0xF0
With the LSB First (MF) set to 0 (selecting LSB):
The sample value is 0x0FF0
The receive buffer (in our little-endian system) reads:
Base Address: 0xF0
Base Address + 1: 0x0F
Is this correct?
