(4) Description of machine cycle column
S indicates the number of machine cycles required for
the instruction having skip function to execute skip
operation. The value of S varies as follows:
Remarks 1: MB indicates an accessible memory bank.
Note:
When no skip ............................................. S = 0
When 1-byte or 2-byte instruction is skipped
When 3-byte instruction (BR !addr, CALL !addr
instructions) is skipped ............................. S = 2

GETI instruction is skipped in one-ma-
chine cycle.
2: In *2, MB = 0 irrespectively of MBE and MBS.
3: In *4 and *5, MB = 15 irrespectively of MBE and
4: *6 to *10 indicate addressable areas.
