Hi,
I have designed a PCB using TDC7200.
VDD=3.3 and I checked that the VREG value is 1.6 during enable mode(I used 1uF external cap).
I set enable pin, then wait for almost 2ms and then set START_MEAS bit (I verified the signals on SPI bus to make sure the signalling is correct), however
I don't see any trigger on TRIGGER pin ( all other registers have their default values)
Any other thing I can check before assuming the chip is dead?
Thanks,
Vahid.
