SBUS<sb>:SPI:FRCondition <FrameCondition>
Defines the start of a frame. A frame contains a number of successive words, at least
one word.
Suffix:
<sb>
.
1...4, index of the serial bus
Parameters:
<FrameCondition> CS | CLKTimeout
CS
Start and end of the frame is defined by the active state of the
slave select signal, see SBUS<sb>:SPI:CSELect:POLarity.
CLKTimeout
Defines a timeout on the clock line SCLK as limiter between two
frames. The timeout condition is used for SPI connections with-
out a CS line.
*RST: CS
Usage: Asynchronous command
Manual operation: See "Frame condition" on page 287
SBUS<sb>:SPI:CSELect:HYSTeresis <Hysteresis>
Sets a value for the hysteresis for the CS channel.
Suffix:
<sb>
.
1...4, index of the serial bus
Parameters:
<Hysteresis>
Usage: Asynchronous command
Manual operation: See "Threshold" on page 285
SBUS<sb>:SPI:CSELect:POLarity <CSPolarity>
Selects if the transmitted signal for the respective line is active high (high = 1) or active
low (low = 1).
Suffix:
<sb>
.
1...4, index of the serial bus
Parameters:
<CSPolarity> ACTLow | ACTHigh
*RST: ACTLow
Usage: Asynchronous command
Manual operation: See "Polarity: MOSI, MISO, CS" on page 285
