:TRIGger:I2S:PATTern:DATA
(see page 798)
Command Syntax
:TRIGger:I2S:PATTern:DATA <string>
<string> ::= "n" where n ::= 32-bit integer in signed decimal when
<base> = DECimal
<string> ::= "nn...n" where n ::= {0 |1|X|$}when
<base> = BINary
<string> ::= "0xnn...n" where n ::= {0,..,9 | A,..,F |X|$}when
<base> = HEX
The :TRIGger:I2S:PATTern:DATA command specifies the I2S trigger data
pattern searched for in each I2S message.
Set a <string> bit to "0" or "1" to set the corresponding bit in the data
pattern to low or high, respectively.
Set a <string> bit to "X" to ignore (mask off) that bit in the data pattern.
Use the "$" character to indicate that the value of the corresponding bit
will not be changed (the existing bit value is used).
When <base> = DECimal, the "X" and "$" characters cannot be entered.
When queried, the "$" character is returned when any bits in the pattern
have the value of "X" and <base> = DECimal. When any bits in a given
nibble have the value of "X" and <base> = HEX, the "$" character is
returned for the corresponding nibble.
NOTE
<base> is specified with the :TRIGger:I2S:PATTern:FORMat command. The default <base>
is DECimal.
NOTE
The :TRIGger:I2S:PATTern:DATA command specifies the I2S trigger data pattern used by the
EQUal, NOTequal, GREaterthan, and LESSthan trigger conditions. If the GREaterthan or
LESSthan trigger condition is selected, the bits specified to be masked off ("X") will be
interpreted as 0's.
NOTE
The length of the trigger data value is determined by the :TRIGger:I2S:RWIDth and
:TRIGger:I2S:TWIDth commands. When the receiver word size is less than the transmitter
word size, the data length is equal to the receiver word size. When the receiver word size is
greater than the transmitter word size, the data length is equal to the transmitter word size.
