15.3.1.4 MTB Base Register (MTB_BASE)
The read-only MTB_BASE Register indicates where the RAM is located in the system
memory map. This register is provided to enable auto discovery of the MTB RAM
location, by a debug agent and is defined by a hardware design parameter. For this
device, the base address is defined by the expression: MTB_BASE[BASEADDR] =
0x2000_0000 - (RAM_Size/4)
Address: F000_0000h base + Ch offset = F000_000Ch

MTB_BASE field descriptions
Field Description
BASEADDR BASEADDR
This value is defined with a hardwired signal and the expression: 0x2000_0000 - (RAM_Size/4). For
example, if the total RAM capacity is 16 KB, this field is 0x1FFF_F000.
15.3.1.5 Integration Mode Control Register (MTB_MODECTRL)
This register enables the device to switch from a functional mode, or default behavior,
into integration mode. It is hardwired to specific values used during the auto-discovery
process by an external debug agent.
Address: F000_0000h base + F00h offset = F000_0F00h
