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.
