*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
Main CR clock
Sub clock divided by 2
Sub CR clock divided by 2
*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
*3 : The clock in case of operating code on FRAM, or Read/Write access to FRAM. Its value is machine clock
divided by 3.
