1. The external clock input range refers to a CPU clock range of 1...64 MHz. Moreover, the PLL usage is
2. The limits on input frequency are 4-12 MHz since the usage of the internal oscillator amplifier is required.
3. The maximum depends on the duty cycle of the external clock signal: When 64 MHz is used, 50% duty
Prescaler operation
When pins P0.15-13 (P0H.7-5) equal ‘001’ during reset, the CPU clock is derived from the
internal oscillator (input clock signal) by a 2:1 prescaler.
The frequency of f
is, the duration of an individual TCL) is defined by the period of the input clock f
The timings listed in the AC Characteristics that refer to TCL can therefore be calculated
using the period of f
Note that if the bit OWDDIS in SYSCON register is cleared, the PLL runs on its free-running
frequency and delivers the clock signal for the Oscillator Watchdog. If bit OWDDIS is set,
then the PLL is switched off.
Direct drive
When pins P0.15-13 (P0H.7-5) equal ‘011’ during reset, the on-chip phase locked loop is
disabled, the on-chip oscillator amplifier is bypassed and the CPU clock is directly driven by
the input clock signal on XTAL1 pin.

limited to 4-12 MHz input frequency range. All configurations need a crystal (or ceramic resonator) to
generate the CPU clock through the internal oscillator amplifier (apart from Direct Drive); on the contrary,
the clock can be forced through an external clock source only in Direct Drive mode (on-chip oscillator
amplifier disabled, so no crystal or resonator can be used).
Also, when the PLL is not used and the CPU clock corresponds to f

be accepted (minimum phase, high or low, again equal to 7.8ns).
