UM012811-0904
causes a Program Counter jump to occur because bit 5 of Working Register R7 passes
the test for a 1. The next instruction executed after the BTJ is the LD instruction. The
eZ8 CPU assembler automatically calculates the desired displacement value of
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.
Assembly Code
BTJ 1, 5, r7, NEXT
NEXT:
LD r0, @r2
Object Code
F6 D7 01
This label is not assembled, but used by the assembler to identify
the destination address (the address of the next instruction).
