I/O Lines Description
Power-On
The PM interrupt line is connected to one of the internal sources of the interrupt controller. Using
the PM interrupt requires the interrupt controller to be programmed first.
In AT32UC3L, the HSB shares the source clock with the CPU. This means that writing to the
HSBSEL register has no effect. This register will always read the same value as CPUSEL.
The Shutdown mode is only available for the “3.3V supply mode, with 1.8V regulated I/O
lines“ power configuration.
