(2) Clock control register (CKC)
(3) Processor clock control register (PCC)
Cautions 1. The default value of the CKC register is 0AH. However, be sure to set 0BH to this register
Cautions 1. Be sure to clear bits 2 to 7 to “0”.
The CKC register is used to control the PLL mode. Before using the PLL mode (PLLCTL.SELPLL bit = 1), be
sure to set the CKC register to 0BH. Unless the CKC register has been set, the operation is not guaranteed.
The CKC register is a special register. Data can be written to this register only in a combination of specific
sequences (see 3.4.7 Special registers).
This register can be read or written in 8-bit units.
Reset sets this register to 0AH.
The PCC register is a special register. Data can be written to this register only in a combination of specific
sequences (see 3.4.7 Special registers).
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 03H.
2. When writing to the CKC register, use command register PRCMD.
2. Set the PCC register after the PLL mode is selected (PLLCTL.SELPLL bit = 1).
3. When writing to the PCC register, use command register PRCMD.
After reset:

during initial settings. The default value of an in-circuit emulator is undefined, but also set
0BH to the register when an in-circuit emulator is used.
