11.1.5 Skip Instructions and the Number of Machine Cycles Required for a Skip

The instruction set of the µPD750008 is designed to organize a program by testing a condition with the
skip function.
When a skip instruction satisfies the skip condition, the immediately following instruction is skipped to
execute the instruction immediately after the skipped instruction.
A skip requires the following number of machine cycles:
(a) When the instruction (to be skipped) immediately following the skip instruction is a 3-byte instruction
(that is, the BR !addr, BRA !addr1, CALL !addr, or CALLA !addr1 instruction): 2 machine cycles
(b) When the instruction (to be skipped) immediately following the skip instruction is an instruction other
than the instructions described in (a) above: 1 machine cycle
