CHAPTER  5   CLOCK   GENERATORS

5.6  Operation of Clock Generator Supplying Clock to Peripheral Hardware 

 

The following two types of clocks are supplied to the peripheral hardware. 
 

•

 Clock to peripheral hardware (f

XP

) 

•

 Low-speed internal oscillation clock (f

RL

) 

 

(1)   Clock to peripheral hardware 

The clock to the peripheral hardware is supplied by dividing the system clock (f

X

).  The division ratio is selected 

by the pre-processor clock control register (PPCC). 
Three types of frequencies are selectable: “f

X

”, “f

X

/2”, and “f

X

/2

2

”.  Table 5-3 lists the clocks supplied to the 

peripheral hardware.

(2)   Low-speed internal oscillation clock 

The low-speed internal oscillator of the clock oscillator for interval time generation is always started after release 
of reset, and oscillates at 240 kHz (TYP.). 
It can be specified by the option byte whether the low-speed internal oscillator can or cannot be stopped by 
software.  If it is specified that the low-speed internal oscillator can be stopped by software, oscillation can be 
started or stopped by using the low-speed internal oscillation mode register (LSRCM).  If it is specified that it 
cannot be stopped by software, the clock source of WDT is fixed to the low-speed internal oscillation clock (f

RL

). 

The low-speed internal oscillator is independent of the CPU clock.  If it is used as the source clock of WDT, 
therefore, a hang-up can be detected even if the CPU clock is stopped.  If the low-speed internal oscillator is used 
as a count clock source of 8-bit timer H1, 8-bit timer H1 can operate even in the standby status. 
Table 5-4 shows the operation status of the low-speed internal oscillator when it is selected as the source clock of 
WDT and the count clock of 8-bit timer H1.  Figure 5-14 shows the status transition of the low-speed internal 
oscillator.
