Section 4 Clock Pulse Generator (CPG)
4.3
Table 4.3 shows the clock operating mode of this LSI.
Table 4.3
Note:
Mode 1: The frequency of the external clock input from the EXTAL pin is multiplied by 8 in the
PLL circuit before being supplied to the on-chip modules in this LSI, which eliminates the need to
generate a high-frequency clock outside the LSI. Since the input clock frequency ranging from 5
MHz to 12.5 MHz can be used, the internal clock (Iφ) frequency ranges from 10 MHz to 80 MHz.
Maximum operating frequencies:
Iφ = 80 MHz, Bφ = 40 MHz, Pφ = 40 MHz, MIφ = 80 MHz, and MPφ = 40 MHz
Table 4.4 shows the frequency division ratios that can be specified with FRQCR.

Clock Operating Mode
To output the clock through the clock output (CK) pin, appropriate settings should be
made in the pin function controller (PFC). For details, refer to section 21, Pin Function
Controller (PFC).
