Chapter 7 Automatic Sending/Receiving function (ASR)
The sample program uses the below internal I/O.
FUN 201 parameters for reading Status Register (SR) FUN 201 parameters for writing Control Register
I/O Description I/O Description
WM0 Result (Return code) WM8 Result (Return code)
WM1 System area WM9 System area
WM2 System area WMA System area
WM3 Control type (Read / write / etc) WMB Control type (Read / write / etc)
WM4 EH-ETH2 slot number, and starting address for SR WMC EH-ETH2 slot number, and starting address for CR
WM5 Address of control bit for reading SR WMD Address of control bit for writing CR
WM6 Address of data for SR (Destination to read) WME Address of data for CR (Source to write)
WM7 Data size for reading SR WMF Data size for writing CR
R100 Execution bit for reading SR R103 Execution bit for writing CR
R101 OK flag for reading SR R104 OK flag for writing CR
R102 Error flag for reading SR R105 Error flag for writing CR
*1: In the case of EHV-CPU, the command of SCRW is used to read or write to the registers.
The following points are different in the sample programs for EHV-CPU.
a) It does not need setting of Address of control bit for reading or writing (WM5, WMD of the above table).
b) Starting I/O No. of Destination (or Source) (WM6, WME of the above table) is set to WM5, WMD (of the above table).
Status Register (SR) destination I/O Control Register (CR) source I/O
