VCC(3.3)[3]

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

external devices; see Section 10

XTAL2

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)

DGND

61 -

digital ground
