Bits 31:0 PORTSIZE[31:0]: current trace port size
Bit n-1 when set indicates that the current port size is n pins. The value of n must be within
the range of supported port sizes (1-4). Only one bit can be set, or unpredictable behaviour
may result. This register must be modified only when the formatter is stopped.
