Macro description
The HSITYPE macro provides the user with information about the current HSI (Hardware-Software Interface). The information is output to a field whose address is stored in a register. The information provided applies to the entire duration of the current BS2000 session.
Only output value (only XS31 hardware is supported):
XS31: Addressable memory area > 16 Mb; all addresses are interpreted as either
24-bit or 31-bit addresses, depending on the addressing mode.
The macro generates a 31-bit interface.
