(Minimum instruction
: Operation clock of the microcontroller. Machine clock can be selected as follow.
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 follow.
• Main clock divided by 2
• PLL multiplication of main clock (select from 1, 2, 2.5 multiplication)
• Subclock divided by 2
• PLL multiplication of subclock (select from 2, 3, 4 multiplication)
• Source clock (no division)
• Source clock divided by 4
• Source clock divided by 8
• Source clock divided by 16
