9.3.4. ETB RAM Read Pointer Register, RRP, 0x014

The RAM Read Pointer Register sets the read pointer used to read entries from the Trace RAM over the APB interface. When this register is written to, a RAM access is initiated. The RAM Read Data Register is then updated. The register can also be read to determine the current memory location being referenced.

This register must not be written to when trace capture is enabled (FtStopped=0, TraceCaptEn=1). If access is attempted, the register is not updated.

Table 9.8 shows the ETB RAM Read Pointer Register bit assignments.
