FXLS8471q - use of RST pin for selecting SPI mode

Question asked by Robert Holland on Feb 2, 2015

I'm testing a prototype but seem to have difficulty establishing SPI mode.

I have an output pin driving the RST pin to control the sequence in software.

My initialisation routine floats SA0/MISO with RST low, then drives RST high for 1ms.

I am monitoring the INT1 pin as described in sections 6.2.3 / 6.2.4 in the data sheet but this sequence seems unclear.

Is there a detailed timing diagram of this reset sequence anywhere?
