4.21.7 Embedded Trace Macrocell (ETM-R4)
The device contains a ETM-R4 module with a 32-bit internal data port. The ETM-R4 module is connected
to a TPIU with a 32-bit data bus; the TPIU provides a 35-bit (32-bit data, 3-bit control) external interface
for trace. The ETM-R4 is CoreSight compliant and follows the ETM v3 specification; for more details see
ARM CoreSight ETM-R4 TRM specification.
4.21.7.1 ETM TRACECLKIN Selection
The ETM clock source can be selected as either VCLK or the external ETMTRACECLKIN pin. The
selection is done by the EXTCTRLOUT[1:0] control bits of the TPIU; the default is '00'. The address of this
register is TPIU base address + 0x404.
Before you begin accessing TPIU registers, TPIU should be unlocked via coresight key and 1 or 2 should
be written to this register.
