writes, “Param1” will display the value of the single-byte parameter. And for twoparameter writes, “Param1” and “Param2” will display the single-byte parameters.
Another example is the DCS Set Column Address command that has two 16-bit
parameters. In this case, “Param1” and “Param2” will display the 16-bit StartColumn
and EndColumn parameters respectively.
Finally, note that when the Param fields are added as mnemonic fields using the “Mnem
Cfg…” button, the actual parameter names are displayed in the mnemonic. For this
reason, in general, the user may always want to have the Param fields selected as fields to
display in the mnemonic.
3.2.2.2.6 LPSeq Field
The LPSeq field indicates the LP sequence state of the CPhy Decoder at the time the
record was recorded. The LP sequence state represents a position in decoding CPhy LP
signaling, for example, the state LP-320 records having seen the sequence LP11, LP10,
LP00 (the first three signaling states of a BTA). The following LP sequence states are
used:6
State
Stop
LP-Rqst
LP-320
LP-3202
BTA
BTA-Exit
LP-3201
LP-Esc
HS-Rqst
HS-Go
LP Seq
LP11
LP11, LP10
LP11, LP10, LP00
LP11, LP10, LP00, LP10
LP11, LP10, LP00, LP10, LP00
LP11, LP10, LP00, LP10, LP00, LP10
LP11, LP10, LP00, LP01
LP11, LP10, LP00, LP01, LP00
LP11, LP01
LP11, LP01, LP00 (In HS Burst)
3.2.2.2.7 PktLen Field
The PktLen field applies to records that contain the first header byte of a packet and
indicates the total number of bytes associated with the packet (including header and CRC
fields).
3.2.2.2.8 VC Field
The VC field applies to records that contain the first header byte of a packet and displays
the 2-bit virtual channel field of the packet. In CSI, note that the value in this field is
selected from a PH with a correct CRC, if one exists in the header. Otherwise, the value
displayed from the first PH in the packet.
3.2.2.2.9 DataType Field
The DataType field applies to records that contain the first header byte of a packet and
displays the 6-bit data type field of the packet. In CSI, note that the value in this field is
6
Note that the CPhy Decoder does not distinguish between the LP000 state called HSPrepare and the HS-0
state called HSZero. The sequence state for this period is called HS-Go.
