Cautions 1. The PLL mode cannot be used at f
Remark Both the CPU clock and peripheral clock are divided by the CKC register, but only the CPU clock is
The CKC register is a special register. Data can be written to this register only in a combination of specific
sequence (see 3.4.7 Special registers).
The CKC register controls the internal system clock in the PLL mode.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 0AH.
