Register explanation
Internal Clock Control/Status Register (ICCS)
bit 31 to bit 7
bit 6 to bit 4
:Reserved [“0”Write, Don’t care for read]
:CLKST (Internal Clock Status)(An initial value is a set point of external terminal CLKSEL2,
CLKSEL1, and CLKSEL0. )
Can know the multiplication rate that CPU works by the bit which shows Internal Clock.
CLKST
bit 3
:CE (Internal Clock Change Enable)(Initial value “0”)
Internal Clock change inable bit.Internal Clock is changed according to the CLKSEL bit according
to this value at sleep mode (low power consumption mode).
1: Internal Clock is changed by the CLKSEL bit.
0: No change Internal Clock.
It is necessary to set “1” in this bit to change Internal Clock before sleep mode (low power con-
sumption mode) is set.
:CLKSEL (Internal Clock Select)
Internal Clock specification bit.
