UM012820-0810 BTJ Instruction

105

The next instruction executed after the BTJ is the LD instruction. The eZ8

CPU assembler automatically calculates the appropriate displacement

value of

01h, allowing the Program Counter to skip the one byte HALT

instruction and jump to the NEXT label that identifies the LD instruction

address. The flags are unaffected.

(the address of the next instruction).
