Low power, low price, low pin count (20 pin)
microcontroller with 2 kbyte OTP
THE OSCILLATOR MUST BE CONFIGURED IN ONE OF
THE FOLLOWING MODES:
– LOW FREQUENCY CRYSTAL
– MEDIUM FREQUENCY CRYSTAL
– HIGH FREQUENCY CRYSTAL
CAPACITOR VALUES MAY BE OPTIMIZED FOR
DIFFERENT OSCILLATOR FREQUENCIES (SEE TEXT)
THE OSCILLATOR MUST BE CONFIGURED IN
THE EXTERNAL CLOCK INPUT MODE.
A CLOCK OUTPUT MAY BE OBTAINED ON
THE X2 PIN BY SETTING THE ENCLK BIT IN
THE P2M1 REGISTER.
A SERIES RESISTOR MAY BE REQUIRED IN ORDER TO
LIMIT CRYSTAL DRIVE LEVELS. THIS IS PARTICULARLY
IMPORTANT FOR LOW FREQUENCY CRYSTALS (SEE TEXT).
