CALLF
• This is a subroutine call which can only be branched to addresses 0800H to 0FFFH.
• The start address (PC+2) of the next instruction is saved in the stack and is branched in the range of
• Only the lower 11 bits of an address are specified (with the higher 5 bits fixed to 00001B).
• The program size can be compressed by locating the subroutine at 0800H to 0FFFH and using this
