#### 6.62.5 PRU Pragmas

`ctable_entry` index constant_address
  Specifies that the PRU CTABLE entry given by index has the value constant_address. This enables GCC to emit LBCO/SBCO instructions when the load/store address is known and can be addressed with some CTABLE entry. For example:

                /* will compile to "sbco Rx, 2, 0x10, 4" */
                #pragma ctable_entry 2 0x4802a000
                *(unsigned int *)0x4802a010 = val;
