Clarification on ULP co-processor REG_WR instruction
Posted: Thu Nov 23, 2017 4:43 am
Am now studying the REG_WR instruction as found here:
http://esp-idf.readthedocs.io/en/latest ... l-register
The docs seem to say that I can write 8 bits from a ULP regsiter into a peripheral register control structure.
However, everything I see to read on it seems to show that the 8 bits of data one supplies are constant operands on the instruction. I'm not sensing that there is a mechanism to write the value of a register into a peripheral control structure.
