58
-
supply voltage (3.3 V
± 0.3 V); supplies internal digital
circuits or it is the tapped out voltage from the internal
regulator; this regulated voltage cannot be used to drive

59
O
crystal oscillator output (12 MHz); connect a fundamental
parallel-resonant crystal; leave this pin open when using an
external clock source on pin XTAL1
XTAL1
60
I
crystal oscillator input (12 MHz); connect a fundamental
parallel-resonant crystal or an external clock source
(leaving pin XTAL2 unconnected)
