Syntax:

• CTR Rd4 BS

Description:

Copies the data from a specified configuration register into register Rd4. The register Rd4 is written through Port 4 (P4). The address of the source configuration register is loaded prior to CTR by LCA instruction.

Note: The value of the configuration register is only available on the low bank, while the high bank is always zero.

Microcode Pattern:

Takes 2 cycles to execute.
    Example: CTR 0xa4 3

Example :

AGU_ED ZERO 0x00000011  !! Generates 0x00000011 on the 
                        !! output of the accumulator
						
LCA                     !! Loads configuration address from 
                        !! the value of the accumulator, i.e., 
                        !! 0x11

CTR 0xa 3               !! Copies configuration address 0x11 
                        !! into the register address 0xa
