ADC_INx pin, current limit for MOD5441x module

I expect that voltage limit for ADC_IN0 to ADC_IN7 will be –0.3 to +3.6 according to datasheet for uP. Anyway there is a possibility to also limit current to the pin as protection against over-voltage. If I understand well maximum current not to disturb the ADC function is 3mA (IADI, table 26 in dat...

FlexBus Data a Address bus in MOD54417

I would like to connect Everspin MR4A08B MRAM Memory to MOD54417 via FlexBus. Memory is 8bit wide x 2MByte. So it has 8 data pins (D0..D7) and 21 address pins (A0..A20). I understand that uP itself support this configuration. But I am not sure about module bus. Is the module bus directly connected t...

Re: UART Boot Port

I need to use UART2 as monitor port. It is possible to change monitor port to UART2?

UART Boot Port

For the module MOD54417-200IR I need to use 2 CANs, I2C and dedicated UART with RTS/CTS.
So I did not find any pin multiplexing solution where UART0 pins could be use as system UART to enter the monitor.
It is possible to redirect Monitor boot UART to another free UART? If yes how?

Re: SD Card On some Modules

I would prefer to use external off module card with 4-bit SDHC with MOD54417.
Is the reference schematic available?
Is this solution also supported by standard kit?

SD Card On some Modules

We would like to use installed SD Card holder on MOD54417 module for logging purpose. - Is the basic development kit NNDK enough or we need to buy some software options? - How is the card connected - SPI mode or 4-bit mode? - What is the expected data rate? - Is there any limitation on other periphe...
