from the basic clock (fc or fs). The timing generator provides the following functions.
The timing generator generates the various system clocks supplied to the CPU core and peripheral hardware
and machine cycle counters.
TBTCR<DV7CK>, that is shown in Figure 2-4. As reset and STOP mode started/canceled, the prescaler
and the divider are cleared to “0”.
1. Generation of main system clock
2. Generation of divider output (
3. Generation of source clocks for time base timer
4. Generation of source clocks for watchdog timer
5. Generation of internal source clocks for timer/counters
6. Generation of warm-up clocks for releasing STOP mode
Configuration of timing generator
The timing generator consists of a 2-stage prescaler, a 21-stage divider, a main system clock generator,
An input clock to the 7th stage of the divider depends on the operating mode, SYSCR2<SYSCK> and
Timer counter, Serial interface, Time-base-timer, divider output, etc. (Peripheral functions)
