OSCALL – Operating system calls

Block SymbolLicensing group: STANDARD

Function Description
The OSCALL block is intended for executing operating system functions from within the REXYGEN system. The chosen action is performed upon a rising edge (off $\to$ on) at the TRG input. However, not all actions are supported on individual platforms. The result of the operation and the possible error code are displayed by the E and iE outputs.

Note that there is also the EPC block available, which allows execution of external programs.

This block does not propagate the signal quality. More information can be found in the 1.4 section.
