10.4.15 Transfer Multiple Main Processor Registers Primitive
10.4.16 Transfer Multiple Coprocessor Registers Primitive
IcAI
The transfer multiple main processor registers primitive transfers long-word
tion and the coprocessor. This primitive applies to general category instruc-
operands between one or more of its data or address registers and the
coprocessor, This primitive applies to general and conditional category in-
structions. Figure 10-35 shows the format of the transfer multiple main pro-
cessor registers primitive.
This primitive uses the CA, PC, and DR bits as previously described. If the
When the main processor receives this primitive, it reads a 16-bit register
transfers. If DR = 1, the main processor reads a long-word operand from the
operand CIR into each register indicated in the register select mask. The
transfer indicated by the DR bit.
The transfer multiple coprocessor registers primitive transfers from 0-16
operands between the effective address specified in the coprocessor instruc-
coprocessor issues this primitive with CA=0 during a conditional category
cessing.
select mask from the register select CIR. The format of the register select
mask is shown in Figure 10-36. A register is transferred if the bit correspond-
ing to the register in the register select mask is set to one. The selected
registers are transferred in the order D0-D7 and then A0-A7.
If DR=0, the main processor writes the contents of each register indicated
in the register select mask to the operand CIR using a sequence of long-word
registers are transferred in the same order, regardless of the direction of
instruction, the main processor initiates protocol violation exception pro-
