19.31.4 MTB Base Register (MTB_BASE)The read-only MTB_BASE Register indicates where the RAM is located in the systemmemory map. This register is provided to enable auto discovery of the MTB RAMlocation, by a debug agent and is defined by a hardware design parameter. For thisdevice, the base address is defined by the expression: MTB_BASE[BASEADDR] =0x2000_0000 - (RAM_Size/4)Address: F000_0000h base + Ch offset = F000_000ChBit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0R BASEADDRWReset x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x* x** Notes:x = Undefined at reset.•MTB_BASE field descriptionsField Description31–0BASEADDRThis value is defined with a hardwired signal and the expression: 0x2000_0000 - (RAM_Size/4). Forexample, if the total RAM capacity is 16 KB, this field is 0x1FFF_F000.19.31.5 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-discoveryprocess by an external debug agent.Address: F000_0000h base + F00h offset = F000_0F00hBit 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10 9 8 7 6 5 4 3 2 1 0R MODECTRLWReset 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0MTB_MODECTRL field descriptionsField Description31–0MODECTRLHardwired to 0x0000_0000Chapter 19 Micro Trace Buffer (MTB)KL04 Sub-Family Reference Manual, Rev. 3.1, November 2012Freescale Semiconductor, Inc. 279
