When used with 4-bit registers, Mi can be M0 - M15 and can store numbers from 0 to 15.
There are sixteen 4-bit registers.

Code Example

Meaning

M2=M2+3

Add the integer number 2 to the value stored in 4-bit register M2.

M2=M3+2

Add the integer number 2 to the value stored in M3 and store the result in 4-bit register M2.

M2=M3+M4

Add the value stored in M4 to the value stored in M3 and store the result in 4-bit register M2..

 

When used with 8-bit registers, Xi can be X0 - X7 and can store numbers from 0 to 255.
There is a maximum of eight 8-bit registers.

Code Example

Meaning

X4=X4+127

Add the integer number 127 to the value stored in 8-bit register X4.

X4=X5+127
