The oscillation stabilization time is the time the CPU operation is stopped to prevent unstable
operation when oscillation starts.
By using bits 0 to 2 (OSTS0 to OSTS2) of the oscillation stabilization time selection register (OSTS),
2¹²/fX, 2¹⁵/fX, or 2¹⁷/fX can be selected.
Remark fX: Main system clock oscillation frequency
