Table reference
A MOVT instruction reads constant data from a specified location of the program memory (ROM) and sets it
in the data buffer.
The function of the MOVT instruction is explained below.
MOVT DBF,@AR: Reads data from a program memory location pointed to by the address register (AR) and
sets it in the data buffer (DBF).
