3.8 Atmel AT32UC3L064
The AT32UC3L064 is the central point of the Atmel AT32UC3L-EK.
3.8.1 Overview
See
, for a logical view of the
AT32UC3L064 in the kit.
The AT32UC3L064 is powered from the power supply block. It can read the current
battery voltage (through an ADCIFB channel), and may control the power supply
block through the Power-Off signal. For a detailed presentation of the power supply
block, see Section
