2.22. TBMAN
TBMAN refers to the testbench manager, which is used during chip development simulations to verify the design.
During these simulations TBMAN allows software running on RP2040 to control the testbench and simulation
environment. On the real chip it has no effect other than providing a single PLATFORM register to indicate that this is the
real chip. This PLATFORM functionality is duplicated in the sysinfo (Section 2.20) registers.
2.22.1. List of Registers
The TBMAN registers start at a base address of 0x4006c000 (defined as TBMAN_BASE in SDK).
