13.5 CLOCK AND TIMING CHARACTERISTICS

Subject to general operating conditions for VDD, fOSC, and TA.

13.5.1 General Timings

Notes:

1. Data based on characterization. Not tested in production.

2. Data based on typical application software.

3. Time measured between interrupt event and interrupt vector fetch.

∆t

c(INST) is the number of tCPU cycles needed to fin-

ish the current instruction execution.

13.5.2 Auto Wakeup RC Oscillator

Note:

1. Data guaranteed by Design.
