CHAPTER 11 INSTRUCTION SET
264 User’s Manual U10676EJ3V0UM
MOVT XA, @BCXA
Function: XA ← ROM (BCXA)
Transfers the lower 4 bits of the table data (8-bit) in the program memory addressed by the B register and the
contents of registers C, X, and A, to the A register, and the higher 4 bits to the X register.
However, on the
µ
PD754244, register B is invalid. Be sure to set register B to 0000B.
The necessary data must be programmed to the table area in advance by using an assembler directive (DB
instruction). The PC is not affected by execution of this instruction.
