BUS:B<x>:SPI
:DATa:SIZe
This command specifies the number of bits per word (data size) for the specified
SPI bus.
Conditions
This command requires a DPO4EMBD application module for 4000 series
models, and an MDO3EMBD application module for MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:SPI:DATa:SIZe <NR1>
BUS:B<x>:SPI:DATa:SIZe?
Arguments
NR1 is the data size of the specified bus.
Examples
BUS:B1:SPI:DATA:SIZE 8 sets the data size to 8 bits per word.
BUS:B1:SPI:DATA:SIZE? might return BUS:B1:SPI:DATA:SIZE 8
indicating the data size is 8 bits per word.
BUS:B<x>:SPI:FRAMING
This command specifies the type of framing to use for the SPI bus.
Conditions
This command requires a DPO4EMBD application module for 4000 series
models, and an MDO3EMBD application module for MDO3000 series models.
Group
Bus
Syntax
BUS:B<x>:SPI:FRAMING {SS|IDLEtime}
BUS:B<x>:SPI:FRAMING?
Arguments
SS specifies to use the SS (non 2-wire) framing type.
IDLEtime specifies to use the Idle Time (2-wire) framing type.
Examples
BUS:B1:SPI:FRAMING SS sets the framing type to SS.
BUS:B1:SPI:FRAMING IDELTIME might return BUS:B1:SPI:FRAMING
IDELTIME
indicating the framing type is set to IDLETIME.
