[SENSe:]DIGital:MEMory:STOP
Syntax
[SENSe:]DIGital:MEMory:STOP (@<ch_list>)
Description
This command stops a buffered (memory) input operation in progress on the 34950A Digital I/O Module. To resume a stopped buffered read, send the [SENSe:]DIGital:MEMory:STARt command. The width of the first channel in each bank (i.e., channels 101 and 201) controls the width of the memory operations (64K x 8 Bits, 64K x 16 Bits, or 32K x 32 Bits). The first channel on the specified bank must be configured as an input prior to starting a buffered read (see CONFigure:DIGital command).
Used With:
34950A Digital I/O Module

The first channel on a bank in the form (@sccc).

Remarks
Depending on the width specified (see CONFigure:DIGital:WIDTh command), the channel numbering is modified as shown below. For example, if you specify the width as a 16-bit WORD, channels 101 and 102 are combined and addressed collectively as channel 101.

This command overrides the pattern comparison mode (see [SENSe:]DIGital:MEMory:COMPare:ACTion command); therefore, you can use the [SENSe:]DIGital:MEMory:STOP command to stop the buffered read if the bank is configured to stop on a pattern compare.
Example
The following program segment starts a buffered read on channels 101 and 201 on the module in slot 3 and then stops the read.
CONF:DIG:WIDTH
WORD,(@3101,3201) !Width

DIG:MEM:SAMP:COUN 200,(@3101,3201) !Sample

DIG:MEM:STAR (@3101,3201) !Start

DIG:MEM:STOP (@3101,3201) !Stop
