At point 8.2.23 of the DWM3000 user manual, we can read about the indirect pointers : “… The indirect register address is needed when accessing the register contents starting at offset > 127.”
Is it correct since the 4 types of SPI command need an offset limited at 6 bits which allows access at 64 bytes of register. Is it correct or not?
Thank you.

Section 2.3.1.2 of the user manual describes how the addresses are sent over SPI.
Registers have a 5 bit address and then a optional offset within that register.
That offset value is 7 bits (6 bits in the second bytes of the transaction and 1 bit in the LSB of the first byte).
This means you can access 32 registers with an offset of up to 127 directly.
