I have a limited number of available MCU ports.
I saw on an earlier post https://e2e.ti.com/support/data-converters/f/73/t/392555?tisearch=e2e-sitesearch&keymatch=afe4490%252520DIAG_END it is mentioned what to do with some of the I/Os if you don't have enough MCU ports.
Can you verify what can be done with each pin if I don't have enough ports to connect to on my MCU? The post didn't clarify everything for me. What should I do with the remaining pins?
Pin 20, AFE_PDNZ: Connect to MCU or RX_DIG_SUP
Pin 21, DIAG_END:
Pin 22, LED_ALM:
Pin 23, PD_ALM:
SPI CHANNELS: all connected
Pin 28, ADC_RDY: I have this connected to MCU
Pin 29, RESETZ: I have this connected to MCU.
Pin 30, CLK_OUT:
Thanks,
Chloe
