Feedback on RISC-V Trace Control Interface Specification - Chapter 9

[ved-rivos]

1. trPibDivider - "After PIB reset value of this pin.."
   reword to "value of this field". The word "safe" should
   be explained.
2. trPibCalibrate - explain what happens to the trace data
   when this bit is 1. Does the Sink backpressure the source
   or drops the packets?
3. Section 9.1 - LSB bytes is redundant. The first bullet
   should be reworded to separately state transmission order
   for bits and bytes.
4. Section 9.1 - "In 16-bit mode" - does that refer to
   trPibMode=12? "16-bit mode" is not defined before and if so
   should replace with the trPibMode value.
5. Section 9.1 - its more accurate to state "even bytes are
   transmitted on TRC_DATA[7:0] and odd bytes on TRC_DATA[15:8]
   as many messages have more then 2 bytes.
6. Section 9.1 - reword first and second sub-bullet of third
   bullet.
7. Section 9.2 - LSB is sometimes used to reference least
   significant byte and sometimes least significant bit. Should
   use consistent terminology. Explain "next bit period"
8. Table 53 - Patters -> Patterns
