P89LPC932A1
8-bit microcontroller with accelerated two-clock 80C51 core
The frequency of this clock output is 1
2 that of the CCLK. If the clock output is not needed
in Idle mode, it may be turned off prior to entering Idle, saving additional power.
7.4 On-chip RC oscillator option
The P89LPC932A1 has a 6-bit TRIM register that can be used to tune the frequency of
the RC oscillator. During reset, the TRIM value is initialized to a factory preprogrammed
value to adjust the oscillator frequency to 7.373 MHz
± 1 % at room temperature.
End-user applications can write to the TRIM register to adjust the on-chip RC oscillator to
other frequencies.
7.5 Watchdog oscillator option
The watchdog has a separate oscillator which has a frequency of 400 kHz. This oscillator
can be used to save power when a high clock frequency is not needed.
7.6 External clock input option
In this conguration, the processor clock is derived from an external source driving the
P3.1/XTAL1 pin. The rate may be from 0 Hz up to 18 MHz. The P3.0/XTAL2 pin may be
used as a standard port pin or a clock output. When using an oscillator frequency
above 12 MHz, the reset input function of P1.5 must be enabled. An external circuit
is required to hold the device in reset at power-up until VDD has reached its
specied level. When system power is removed, VDD will fall below the minimum
specied operating voltage. When using an oscillator frequency above 12 MHz, in
some applications, an external brownout detect circuit may be required to hold the
device in reset when VDD falls below the minimum specied operating voltage.
