5.2 Configuration of Clock Generator
224
(3) Internal low-speed oscillation clock (clock dedicated to watchdog timer)
Remarks 1. f
Note
The clock generator includes the following hardware.
Note
Control registers
Oscillators
• Internal low-speed oscillator
This circuit oscillates a clock of f
The internal low-speed oscillation clock cannot be used as the CPU clock. The only hardware that operates
with the internal low-speed oscillation clock is the watchdog timer.
Oscillation is stopped when the watchdog timer stops.
The 78K0R/IB3 doesn’t have the subsystem clock.
The 78K0R/IB3 doesn’t have the XT1 oscillator.
2. The watchdog timer stops in the following cases.
Item
• When bit 4 (WDTON) of an option byte (000C0H) = 0
• If the HALT or STOP instruction is executed when bit 4 (WDTON) of an option byte (000C0H) = 1
IL
: Internal low-speed oscillation clock frequency
and bit 0 (WDSTBYON) = 0
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)
40 MHz high-speed oscillation control register (DSCCTL)
Peripheral enable registers 0, 1, 2 (PER0, PER1, PER2)
Operation speed mode control register (OSMC)
X1 oscillator
XT1 oscillator
Internal high-speed oscillator
Internal low-speed oscillator
