(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 division 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 division 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 a multiplier from 2, 2.5, 3 and 4.)
Main CR clock
Subclock divided by 2
Sub-CR clock divided by 2
*2: This is the operating clock of the microcontroller. A machine clock can be selected from the following.
Source clock (no division)
Source clock divided by 4
Source clock divided by 8
Source clock divided by 16
