These register groups (16 registers per group)
are potentially reserved
The amount of reserved registers depends on
the number of endpoints used in the program.
(8 registers are used per endpoint).
– Registers common to other functions.
– In particular, double-check that any registers

ing base vector addresses that entries in the Inter-
