Syntax
Syntax: jmp_= register1, register2, function
- register1 = Register to compare
- register2 = Register to compare with
- function = Function to jump to if conditions are true.
Use
Used to compare the value of a register with another register. If they are equal go to function. To compare register with integer value use jmpi_=
Example
100: leti R1, 00000001
101: leti R2, 00000002
jmp_= R1, R2, 102 //If R1 is equal to R2 go to function 102
addi R1, 00000001
jmp 101
ret
102: nop //This example does nothing.
ret
