7.3 Registers Controlling Clock Generator
(1) Clock operation mode control register (CMC)
R01UH0106EJ0300 Rev.3.00
Oct 01, 2010
Remark f
The following eight registers are used to control the clock generator.
• Clock operation mode control register (CMC)
• System clock control register (CKC)
• Clock operation status control register (CSC)
• Oscillation stabilization time counter status register (OSTC)
• Oscillation stabilization time select register (OSTS)
• 20 MHz internal high-speed oscillation control register (DSCCTL)
• Peripheral enable registers 0, 1, 2
• Operation speed mode control register (OSMC)
Note
Note
This register is used to set the operation mode of the X1/P121, X2/EXCLK/P122, XT1/P123, and XT2/P124
and to select a gain of the oscillator.
The CMC register can be written only once by an 8-bit memory manipulation instruction after reset release. This
register can be read by a 1-bit or 8-bit memory manipulation instruction.
Reset signal generation clears this register to 00H.
The PER2 register is only mounted in the 78K0R/KC3-L, 78K0R/KD3-L, and 78K0R/KE3-L.
The 78K0R/KC3-L (40-pin) doesn’t have the XT1 and XT2 oscillator.
