Fujitsu MB89140 Series Hardware Manual page 3

PREFACE
The terms in this manual are defined as follows:
(1) A clock cycle is one clock cycle of the oscillation frequency.
(2) A system clock cycle is the clock frequency divided by the gear function (see 2.2). One cycle time of the
system clock varies with the settings of the CS1 and CS0 bits of the SYCC register. With some internal
resources, the gear change will cause changes in operating speed. See 3.4 for details.
