11.1
The oscillator consists of a clock pulse generator (CPG) block and a watchdog timer (WDT)
block.
The CPG generates clocks supplied to this LSI and controls the power-down modes.
The WDT is a single-channel timer that counts the clock settling time and is used when clearing
standby mode and temporary standbys, such as frequency changes. It can also be used as an
ordinary watchdog timer or interval timer.
11.1.1
The CPG has the following features:
• Seven clock modes: Selection of seven clock modes according to the frequency range to be
• Three clocks generated independently: An internal clock (Iφ) for the CPU and cache; a
• Frequency change function: Internal and peripheral clock frequencies can be changed
• Power-down mode control: The clock can be stopped for sleep mode and standby mode and
The WDT has the following features:
• Can be used to ensure the clock settling time:
• Can switch between watchdog timer mode and interval timer mode.
• Generates internal resets in watchdog timer mode:
