HI NXP team,

It's a beautiful weather after hot summer day !!

How many I2S could be possible using SGPIOs in LPC4357 ?

I saw the user manual and found out that LPC43xx has 2 I2S and 16 SGPIO pins.
In a previous question, I knew that NXP team changed SGPIO into 2 I2S channels and made 7.1 audio output.
(including 2 I2S..) therefore, 4 I2S would be possible.

however, LPC43xx has 16 SGPIO pins and someone mentioned that If clock and etc pins shared, more I2S would be supported.

Please, Answer my simple question.

thank you.
