Expand description
Field POINTER
writer - Trace packet location pointer. Because a packet consists of two words, the POINTER field is the location of the first word of a packet. This field contains bits [31:3]
of the address, in the SRAM, where the next trace packet will be written. The field points to an unused location and is automatically incremented. A debug agent can calculate the system address, on the AHB-Lite bus, of the SRAM location pointed to by the POSITION register using the following equation: system address = BASE + ((P + (2AWIDTH - (BASE MOD 2AWIDTH))) MOD 2AWIDTH). Where P = POSITION AND 0xFFFF_FFF8. Where BASE is the BASE register value
