System clock controller

The system clock controller generates the system clock signal (f

SYS

) for the CPU core and internal I/O.

It contains two oscillation circuits and a clock gear circuit for high-frequency (fc) operation. The register

SYSCR1<SYSCK> changes the system clock to either fc or fs, SYSCR0<XEN> and SYSCR0<XTEN>

control enabling and disabling of each oscillator, and SYSCR1<GEAR0 to GEAR2> sets the

high-frequency clock gear to either 1, 2, 4, 8 or 16 (fc, fc/2, fc/4, fc/8 or fc/16). These functions can

reduce the power consumption of the equipment in which the device is installed.

The combination of settings <XEN> = 1, <XTEN> = 0, <SYSCK> = 0 and <GEAR0~GEAR2> = 100

will cause the system clock (f

SYS

) to be set to fc/32 (fc/16

1/2) after a Reset.

For example, f

SYS

is set to 0.5 MHz when the 16-MHz oscillator is connected to the X1 and X2 pins.

(1) Switching from Normal Mode to Slow Mode

When the resonator is connected to the X1 and X2 pins, or to the XT1 and XT2 pins, the warm-up

timer can be used to change the operation frequency after stable oscillation has been attained.

The warm-up time can be selected using SYSCR2<WUPTM0,WUPTM1>.

This warm-up timer can be programmed to start and stop as shown in the following examples 1

and 2.

Table 3.3.1 shows the warm-up time.

Note 1: When using an oscillator (other than a resonator) with stable oscillation, a warm-up timer is

not needed.

Note 2: The warm-up timer is operated by an oscillation clock. Hence, there may be some variation

in warm-up time.
