The ETM clock source can be selected as either VCLK or the external ETMTRACECLKIN terminal. The selection is chosen by the EXTCTLOUT[1:0] control bits of the TPIU (default is '00'). The address of this register is the TPIU base address + 0x404.
Before the user begins accessing TPIU registers, the TPIU should be unlocked through the CoreSight key and 1 or 2 written to this register.
