If Working Register R7 contains the value
that begins the following code segment:
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 BTJNZ is the LD instruction.
The eZ8 CPU assembler automatically calculates the desired displacement value of
01H
the NEXT label that identifies the LD instruction address. The flags are unaffected.
