Note:
STM32W108 JTAG TAP connection
The STM32W108 MCU integrates two serially-connected JTAG TAPs in the following order;
the TMC TAP dedicated for Test (IR is 4-bit wide) and the Cortex™-M3 TAP (IR is 4-bit
wide).
To access the TAP of the Cortex-M3 for debug purposes:
1.
2.
3.
Important: Once Serial-Wire is selected using the dedicated ARM JTAG sequence, the
TMC TAP is automatically disabled (JTMS forced high).
First, it is necessary to shift the BYPASS instruction of the TMC TAP.
Then, for each IR shift, the scan chain contains 8 bits (= 4 + 4) and the unused TAP
instruction must be shifted in using the BYPASS instruction.
For each data shift, the unused TAP, which is in BYPASS mode, adds 1 extra data bit in
the data scan chain.
