Hi,
trying to modify the Starterware McASP example I am not sure how to set the receive TDM time slot register (RTDM) correctly:
The aim is just to receive 4 adc channels (no TX activity as demonstrated in the example).
The number of I2S data lines has been increased from 1 to 2. AXR(0) and AXR(1) shall be the receive serializers.
Per I2S signal there is a left and right signal with 24 bits each.
Would it be correct to set the slot register RTDM to 0x0F?
I.e. 4 slots 3...0 with 4 adc channels?
SDOUT1 and SDOUT2 are the data lines representing the I2S signals (coming out from an adc PCM4204).
How can I make sure that the data always is received in the same order? All 4 channels are sampled
simoultaneously.
Does anybody know an answer?
Thank you.
Regards,
Martin H.
