50.3.13 PST Buffer (PSTB)
The PST trace buffer contains 64 six-bit entries, packed consecutively into 12 longword
locations. See the following figure for an illustration of how the buffer entries are packed.
The write pointer for the trace buffer is available as CSR2[PSTBWA]. Using this pointer,
it is possible to determine the oldest-to-newest entries in the trace buffer.
