S32K312 has 32 I/O pins, 8 timers, 8 shift registers and 16 bits in counter.

So, I have below several questions for you.

Please check and reply it to me.

 

Q1. Max SPI channels supported in S32K312 using Flex IO

I think that SPI needs 4 lines(CLK, CS, MOSI and MISO). 

Referring to below table1, max SPI channels  are 4 in SPI master(SPI leader) and SPI slave(SPI follower).

 

Q2. Max UART channels supported in S32K312 using Flex IO

I think that UART at least needs 2 lines(UART TXD, UART TXD).

Referring to below table 1, max UART channels are 4.

 

Q3. Max I2C channels supported in S32K312 using Flex IO

I think that I2C  needs 2 lines(SCL, SDA).

Referring to below table 1, max master I2C channels are 4. I2C slave is not supported using Flex IO

 

Q4. Max I2S channels supported in S32K312 using Flex IO

I think that I2S needs 4 lines(BCLK, LRCK, DATA IN, DATA OUT).

Referring to below table, max I2S channels are 4 in I2S mater(I2S leader) and max I2S channels are 2 in  I2S slave(I2S follower)

 

Q5. Max Camera interface channels supported in S32K312 using Flex IO

Referring to below table, max camera interface are 2 because 11 camera signals are used.

 

Q6. Max 8080 LCD interface channels supported in S32K312 using Flex IO

Referring to below table, max 8080 LCD interface are 2 because 12 LCD signals are used
