PRODUCTION DATA
Refer to the PDF data sheet for device specific package drawings
Trace capability from the Cortex-M4 is supported on the CM subsystem.
The Cortex-M4 supports two trace interfaces:
Both options are supported on this device. Figure 7-111 shows the high-level clock and signal hook-up to and from the TPIU.
Table 7-15 lists the key attributes of the two trace data export mechanisms. For more details about TPIU and trace mechanisms, see the Arm Architecture Reference Manual.
ATTRIBUTE PARALLEL TRACE | SERIAL WIRE TRACE | PARALLEL TRACE |
---|---|---|
Protocol | UART Protocol/Manchester-encoded data stream | Trace Data changes on both edges of TRACECLK. |
Data throughput rate | Frequency(CMHCLK)/(TPIU_ACPR + 1) | Frequency(CMHCLK)/2 |
You must configure the GPIO mux to select a trace function on the GPIO pin to use it.
