• ICP (In-circuit Flash Programming) interface multiplexed with one of the GPIO’s.

• Intelligent Power-On Reset (POR) to provide reduced POR time on detection 

of stable clock from external crystal oscillator or resonator.

• Low-voltage and high-voltage detection flags.

• Programmable Watchdog Timer (WDT)/POR circuits.

• Two on-board analog comparators with independent reference voltages and

programmable interrupt polarity.

• User-selectable options through option bit Flash coding (ON/OFF):

–

–

16-bit addressability for stack pointer

–

No division, divide by 2, divide by 16, or divide by 32 of external clock to system

clock



All signals with an overline, “ ”, are active Low. For example, B/W, in which WORD is

active Low, and B/W, in which BYTE is active Low.

Power connections use the conventional descriptions listed in Table 2.
