Trace data can be exported off-chip to an external equipment through the device trace port, associated with the TPIU module. In this device, the TPIU provides support for up to data pins plus a dedicated export clock and a control signal. Table 13-2 describes the trace port signals.
Pin Name | TPIU Signal Name | I/O Type(1) | Description |
---|---|---|---|
TRC_CLK | TRACECLK | O | Trace Clock |
TRC_CTL | TRACECTL | O | Trace Control |
Although the TPIU is internally configured for a maximum port size of 32 bits (this is reflected in the TPIU Supported Port Size Register), the actual TPIU supported port size is maximum bits. This is defined by the number of device pins available for trace.
Trace port pins are shared with other functional (application) pins on the device boundary. To use the trace port, the user must program the device pin manager (CTRL_MMR) properly. Pin multiplexing is provided in section Pin Multiplexing in device Data Manual, and associated pad configuration registers are described in the Control Module (CTRL_MMR) TRM chapter.
