6.4
The internal functions of this LSI operate synchronously with the system clock (Iφ), the peripheral
module clock (Pφ), or the external bus clock (Bφ). Table 6.1 shows the synchronization clock and
their corresponding functions.
Table 6.1
The frequency of each synchronization clock (Iφ, Pφ, and Bφ) is specified by the system clock
control register (SCKCR) independently. For further details, see section 21, Clock Pulse
Generator.
There will be cases when Pφ and Bφ are equal to Iφ and when Pφ and Bφ are different from Iφ
according to the SCKCR specifications. In any case, access cycles for internal peripheral functions
and external space is performed synchronously with Pφ and Bφ, respectively.
