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

instruction). The PC is not affected by execution of this instruction.
