Notes: 1. "TSTOP" indicates that if the crystal oscillator stops over the value of TSTOP, the system

reset occurs.

2. "POR" denotes Power On Reset.

3. "VPOR1" indicates that POR occurs when VDD falls from VDD to VPOR1 and again rises

up to VDD.

4. "VPOR2" indicates that POR does not occur when VDD falls from VDD to VPOR2 and

again rises up to VDD.
