Cortex-M3 TAP

The TAP of the ARM Cortex-M3 integrates a JTAG ID code. This ID code is the ARM default
one and has not been modified. This code is only accessible by the JTAG Debug Port.
This code is 0x3BA00477 (corresponds to Cortex-M3 r1p1)
Only the DEV_ID(15:0) should be used for identification by the debugger/programmer tools.
26.6.4

Cortex-M3 JEDEC-106 ID code

The ARM Cortex-M3 integrates a JEDEC-106 ID code. It is located in the 4KB ROM table
mapped on the internal PPB bus at address 0xE00FF000_0xE00FFFFF.
This code is accessible by the JTAG Debug Port (4 to 5 pins) or by the SW Debug Port (two
pins) or by the user software.
