Hello:
I have two questions regarding ADS5407's SPI as below.
1. To reset ADS5407 SPI internal registers, keeping LOW at pin SRESET (pin number is B12) for a certain time (then back to HIGH) is okay? Or must assert a HIGH-to-LOW falling edge? I am saying this, because, we only need to reset SPI once that happens during the power up, if a LOW level (no falling edge necessary) is okay, we can simply have a Resistor+Capacitor+Schimitt-Gate circuit that will keep the pin SRESET LOW during the power up (no previous HIGH level) and then keep HIGH. Otherwise we have to have a microprocessor or FPGA to provide the falling edge to reset the SPI.
2. We will use two ADS5407 together by tying two SDIOs (pin number A11) together, and two SCLK (pin A12) together, and with individual SDENBs (pin number A13), SDOs (pin number A10) are not used, this approaching is working?
Thank you very much.
