Overview
The XMEGA A4 includes a 16-bit Real-time Counter (RTC). The RTC can be clocked from an
accurate 32.768 kHz Crystal Oscillator, the 32.768 kHz Calibrated Internal Oscillator, or from the
32 kHz Ultra Low Power Internal Oscillator. The RTC includes both a Period and a Compare
register. For details, see Figure 19-1.
A wide range of Resolution and Time-out periods can be configured using the RTC. With a max-
imum resolution of 30.5 s, time-out periods range up to 2000 seconds. With a resolution of 1
second, the maximum time-out period is over 18 hours (65536 seconds).
