Multi-Clock Function

The internal functions of this LSI operate synchronously with the system clock (Iφ) or the
peripheral module clock (Pφ). Table 6.1 shows the synchronization clock and their corresponding
functions.
Table 6.1 Synchronization Clocks and Their Corresponding Functions
Synchronization Clock
Iφ
Pφ
The frequency of each synchronization clock (Iφ and Pφ) is specified by the system clock control
register (SCKCR) independently. For further details, see section 18, Clock Pulse Generator.
