There are up to 20 manager ID (MID) registers. The actual number of registers is set by a user parameter at configuration time and can be read in the N_MANAGER_IDS register.

MID registers are located in consecutive registers starting at address 0x100. The MID register for manager ID <m> is located at address 0x100 + <m>*4, where <m> goes from 0 up to (N_MANAGER_IDS-1). The highest possible MID register address, for manager ID 19, is 0x14C.

Registers for unimplemented MIDs read as zero.
