... It can be driven low during an interrupt acknowledge cycle can also serve as a general-purpose output. The /RESET_IN pin is an external input that is used to reset the Rabbit 2000 and the onboard peripheral circuits on the RabbitCore module.

... D/A converters from the more accurate 4.096 V reference is best. However, should a customer desire more dynamic range (0–5 V rather than 0–4.096 V), the jumper across JP3 can be set to power the D/A converters from +V. When powered from the +V supply, the outputs of the D/A converters will always be ratiometric, independent of whether the zener diode is installed ...
Page 33
... Only the BL2000 and the BL2020 models are stuffed with D/A converters. The D/A con- verters provide only a voltage output. This means that in order to maintain the maximum accuracy of the D/A converters, only a small amount of current should be drawn from the D/A converter output (of the order of µA). ...

It reduces the battery voltage to the SRAM and to the real-time clock, thereby limiting the current consumed by the real-time clock and lengthening the battery life. • It ensures that current can flow only out of the battery to prevent charging the battery. • A voltage, VOSC, is supplied to U14, which keeps the 32.768 kHz oscillator working when the voltage begins to drop.
