ETM
The device contains an ARM Cortex-R4F External Trace Macrocell (ETM-R4) with a 32bit data port. The
ETM-R4 module is connected to a Test Port Interface Unit (TPIU) with a 32bit data bus. The ETM-R4 is
CoreSight compliant and follows the ARM ETM v3 specification; for more details see ARM CoreSight
ETM-R4 TRM specification Revr0p0. The ETM-R4 supports "half rate clocking" only.
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'.
