(2) Source Clock/Machine Clock
(VCC
= 5.0 V ± 10%, AVSS = VSS = 0.0 V, TA = 40 °C to + 105 °C)
*1 : Clock before setting division due to machine clock division ratio selection bit (SYCC : DIV1 and DIV0) . This
source clock is divided by the machine clock division ratio selection bit (SYCC : DIV1 and DIV0) , and it becomes
the machine clock. Further, the source clock can be selected as follows.
Main clock divided by 2
PLL multiplication of main clock (select from 1, 2, 2.5, 4 multiplication)
Sub clock divided by 2
PLL multiplication of sub clock (select from 2, 3, 4 multiplication)
*2 : Operation clock of the microcontroller. Machine clock can be selected as follows.
Source clock (no division)
Source clock divided by 4
Source clock divided by 8
Source clock divided by 16
