I am looking for away to check how many entries have been received by the RMT RX.
There is a status register in the SDK: RMT_CH0STATUS_REG (for channel zero at base+0x60), but the content is undocumented.
Default value for mee seems to be: 0x1C01C0 and changes to something like 0x31C01CE when data is received where the lower bits depend on the count.
More info would be appreciated.

RMT status register
Re: RMT status register
That does indeed look like an omission in the ESP32 Technical Reference manual. There appears to be a bunch of RMT registers described in the headers not documented.
