WebMar 9, 2024 · I've got an 8 bit input ("A") and an 8 bit output ("B"). I'm trying to set B's upper nibble to A's lower nibble and B's lower nibble to 6. Obviously 6 is just 0x6, but I'm having … WebSolution: –first we shall get the upper nibble of r7 in r6. Then we swap nibbles of r7 and make OR operation with r6 so the upper and lower nibbles are duplicated Mov a, r7 ; get the content in acc Anl a, #0F0h ; mask lower bit Mov r6, a ; send it to r6 Swap a ; xchange upper and lower nibbles of acc Orl a, r6 ; OR operation

WebJul 30, 2024 · To get the nibbles, we have to mask at first. So we need to mask the lower nibble and upper nibble and store them into different registers. The upper nibble will be shifted to the right four bits to make it lower nibble. Then we can perform the AND operation, and store it to the memory location F051. Input how roth ira grow
