Every device must have a unique address for the read functionality to work. If, for any reason, two devices are assigned with the same address, it is likely that broadcast and stack reads do not work. Additionally, reads to the doubled address result in destroyed communication. Care must be taken to assign independent address for every device. There are three ways to address the device: using NVM burn on the DEVADD_OTP[ADD], using auto-addressing, and using GPIO addressing.
