5.2.2 Register description
The following registers exist for each signal channel of the oscilloscope terminal. This means these registers
exist
• once on the single-channel KL3361;
• twice on the two-channel KL3362.
R0: Raw ADC value
Raw value of the analog/digital converter.
R6: Diagnostic register
In a later firmware version, the diagnostic register will be used to provide diagnostic information about the
state of the oscilloscope terminal.
R7: Command register
This register can be used to transfer commands to the oscilloscope terminal.
Commands
Command 0x0201: WriteEnvCurvToRAM
Writes the sampling values into the RAM envelope curve (Teach-in method).
Return value: 0x201
Command 0x0202: WriteEnvCurvToFLASH
Writes the sampling values into the RAM envelope curve and the flash envelope curve (Teach-in method).
Return value: 0x202
ROM register
The terminal uses two channels for assigning a byte/word/word data structure. This structure is not
supported by couplers that do not have the BK200 switch functionality. In this case, read access to the
second register set is not available.
The terminal always reports with a shift register length of 5 bytes (see general terminal documentation).
R8: Terminal description
Register R8 contains the terminal identifier in hexadecimal coding:
KL3361: 0x0D21 (3361
dec
)
KL3362: 0x0D22 (3362
dec
)
