Datasheet

Other two modes called External (EXT Wave) and disable (OFF mode) are provided. For
EXT Wave, the drive is disabled and an external source of clock within CMOS level
based in analog oscillator supply can be used. When OFF, EXTAL is pulled down by 240
Kohms resistor and the feedback resistor remains active connecting XTAL through
EXTAL by 1M resistor.
