Operation
Tcc
The Tcc instruction does not allow the following condition codes: HI, LS, NN, and NR.
CMP
TGT
In this example, the contents of the 16-bit X0 register are transferred to the 36-bit A accumulator, and
the contents of the 16-bit R0 address register are transferred to the 16-bit R1 address register if the
specified condition is true. If the specified condition is not true, a NOP is executed.
The condition codes are tested but not modified by this instruction.
