CMOS osc.-s TEST
! notice the word "test" above !!!
originally with j-FET (← to cancel out BJT feedback to quartz) and BJT (← the low power side) while i realized the j-FET can pretty much do the thing on it's own . . .
the copy paste from NXP-s datasheet (the R3 + diodes added as a speculative
startup booster /
frequency booster /
"alternate compile" of the above prev. (not thoroughly studied !!!)
what the NXP d/s does not tell you . . . about 32kHz quartz (the "C5" is the type of magic wand here)
