Hi Dan,
After tooling around a little with reading and writing registers I’ve arrived
at the point where it’s time to initialize/configure the part.
Looking at the User Manual and your notes, it seems that the place to start is
by setting LDO_KICK and BIAS_KICK in the OTP_CFG reg at 0x0B:0x08,
and then to supplement that basic step with a few manual “fixes”. However,
after writing back LDO_KICK and BIAS_KICK I do not see any part of the
values from OTP (BIASTUNE_CAL / LDOTUNE_CAL) appearing in their
respective operating registers BIAS_CTRL / LDO_TUNE after the kick. These
2 registers were zeroed before the kick and remain zero after the kick. So the kick appears to do nothing. Is this what you see?
Thx
Glen
