–
– Clears (0) to SIOF flag and starts serial interface transmit/receive.
V23 = 0: (SIOF) =1
–
–
–
–
–
–
– Clears (0) to SIOF flag and skips the next instruction when the contents of bit 3 (V23) of interrupt control reg-
ister V2 is “0” and contents of SIOF flag is “1.” When V23 = 1: This instruction is equivalent to the NOP
instruction.
