*1 : The previous state is held.
*2 : However, SCLK is 2 division or 4 division of the clock inputted to the low-speed oscillation pin (X0A and
X1A) or internal CR oscillation clock. The division ratio is set by the SCDS bit of the PLL/subclock control
register (PSCCR). (See "CHAPTER 5 CLOCKS".)
See Table 12.1-1 for the interval time.
