User manual
Figure 2
The AHB peripheral area is 2 MB in size and is divided to allow for up to 128 peripherals.
On the EM773, the GPIO ports are the only AHB peripherals. The APB peripheral area is
512 kB in size and is divided to allow for up to 32 peripherals. Each peripheral of either
type is allocated 16 kB of space. This allows simplifying the address decoding for each
peripheral.
All peripheral register addresses are 32-bit word aligned regardless of their size. An
implication of this is that word and half-word registers must be accessed all at once. For
example, it is not possible to read or write the upper byte of a word register separately.
