each trace buffer entry. In Detail mode CINF comprises of R/W and size access information (CRW and
CSZ respectively).
Single byte data accesses in Detail Mode are always stored to the low byte of the trace buffer (DATAL)
and the high byte is cleared. When tracing word accesses, the byte at the lower address is always stored to
trace buffer byte1 and the byte at the higher address is stored to byte0.

The format of the bits is dependent upon the active trace mode as described below.
Field2 Bits in Detail Mode
In Detail Mode the CSZ and CRW bits indicate the type of access being made by the CPU.
