RT1010: How many SAI1 interface has data input lines?

anton_glukhov — Wed, 25 Nov 2020 11:46:12 GMT

Hi,

According to the datasheet for RT1010, it says SAI1 has 2 RX and 2 TX data lines. But, I cannot find SAI1-RXD1 data line(only RXD0 presented). There is no such pin in MCUxpresso. Could you please clarify what is the pin for RXD1? I would like to use both RXD0 and RXD1 of SAI1 interface.

Thanks!

Hi,
Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
1) Could you please clarify what is the pin for RXD1? I would like to use both RXD0 and RXD1 of the SAI1 interface.
-- After checking, the SAI1 seems only to have the RXD0 data line, and I'll inform you later after confirming with the AE team.
Have a great day,
TIC

Hi,
Sorry for the reply late.
On Friday of last week, the AE team replied that RXD1 is multiplexed with TXD1 through software config.
Have a great day.
