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 clock for the PM bus interface (CLK_PM) is generated by the Power Manager. This clock is
enabled at reset, and can be disabled in the Power Manager, whoever if disabled it can only be
re-enabled by a reset.
The Shutdown mode is only available for the “3.3V supply mode, with 1.8V regulated I/O
lines“ power configuration.
