4.2.2 The count clock of OS Timer

The count clock of OSTM is decided by the Option Byte value. It's possible to refer to the Option Byte value

in CubeSuite+ property.

Please specify the value in bit4,bit3 as follows.

Even if bit4,bit3 of Option Byte of the selected device have the different feature, these bits are used to

decide the count clock of OSTM by CubeSuite+ Simulator for V850E2 supporting OS Timer.
