Msp430 move function to ram
WebDuring a block transfer, the CPU is halted until the complete block has been transferred. The block transfer takes 2 × MCLK × DMAxSZ clock cycles to complete. CPU execution resumes with its previous state after the block transfer is complete. In repeated block transfer mode, the DMAEN bit remains set after completion of the block transfer. The Webmoves the hexadecimal number 280 (0x280) to register sp which is a second register in the cpu memory map (Fig.2.), · two-operand move opcode becomes 4 (0100b) · source register (S-reg): we are using here the immediate addressing which means that the number is stored directly in the command. It is pointed out by the number in the
