Question:
For MAX22190, can the digital input status be read from the LEDs instead of reading back through SPI serial interface?
Answer:
Yes, with MAX22190 the digital input status can be read from the LEDs instead of the SPI serial interface. However, if customer is not using the SPI serial interface to read back digital input status, the customer also cannot read back all the diagnostic features of the device such as wire break detection, CRC, thermal shutdown, VDD24 monitoring. Customers not using the SPI serial interface should consider using the MAX22195.
