With this primitive, a general category instruction can change the main pro-

Both the transfer status register and the scanPC primitive transfers values
Bit [8], the SP bit, selects the scanPC option. If SP = 1, the primitive transfers
both the scanPC and status register. If SP=O, only the status register is
If SP = 0 and DR = O, the main processor writes the 16-bit status register value
