(2) Source Clock/Machine Clock
(VCC = 5.0 V
± 10%, VSS = 0.0 V, TA = 40° C to +85° C)
*1: This is the clock before it is divided according to the division ratio set by the machine clock divide ratio select
bits (SYCC:DIV1, DIV0). This source clock is divided to become a machine clock according to the division
ratio set by the machine clock divide ratio select bits (SYCC:DIV1, DIV0). In addition, a source clock can be
selected from the following.
Main clock divided by 2
PLL multiplication of main clock (select from 2, 2.5, 4 multiplication)
Main CR clock divided by 2
Subclock divided by 2
Sub-CR clock divided by 2
