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.
8.2.6
Clock output
The P89LPC920/921/922/9221 supports a user-selectable clock output function on
the XTAL2/CLKOUT pin when crystal oscillator is not being used. This condition
occurs if another clock source has been selected (on-chip RC oscillator, watchdog
oscillator, external clock input on X1) and if the Real-Time clock is not using the
crystal oscillator as its clock source. This allows external devices to synchronize to
the P89LPC920/921/922/9221. This output is enabled by the ENCLK bit in the TRIM
register. 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.
8.3 On-chip RC oscillator option
The P89LPC920/921/922/9221 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
pre-programmed 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.
8.4 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.
8.5 External clock input option
In this conguration, the processor clock is derived from an external source driving
the XTAL1/P3.1 pin. The rate may be from 0 Hz up to 12 MHz. The XTAL2/P3.0 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.
