I just noticed that in Table 26 of Rev A of the datasheet, the following has been inserted:
Bit 14 (CHANNEL_SEL) of COMPMODE must be set to the same current channels.
I currently use the CHSIGN register to monitor the direction of power on all 6 channels, and use the REVxPSEL bits in the ACCMODE register to select which bank of 3 channels I'm looking at. However, I don't currently do anything with the COMPMODE register. While I'm happy to comply with this requirement, I'd like to better understand the risks of not complying, so I know what to look out for in our existing releases. If I set the bits in the ACCMODE register, but not in the COMPMODE register, what happens?
It was this old thread that got me to where I am now:
re-reading it, I do see it was suggested that
did you also set the bits 7 (REVRPSEL) and 6 (REVAPSEL) to 1
I guess I didn't pick up on the significance of the word also and instead focused on this part of the reply:
The bit 14 (CHANNEL_SEL) in COMPMODE only identifies the phases that are monitored from the power quality perspective.
Since I don't use the power quality stuff, I assumed (incorrectly it now seems) that I didn't need to mess with the COMPMODE bits.
