(4) Explanation of number of machine cycles column
S denotes the number of machine cycles required by skip operation when a skip instruction is executed.
The value of S varies as follows.
When no skip is made: S = 0
When the skipped instruction is a 1- or 2-byte instruction: S = 1
When the skipped instruction is a 3-byte instruction
Note
: S = 2
Note
3-byte instruction: BR !addr, BRA !addr1, CALL !addr or CALLA !addr1 instruction
Caution The GETI instruction is skipped in one machine cycle.
One machine cycle is equal to one cycle of CPU clock (= t
CY
); time can be selected from among four types
by setting PCC.
