The TPU3 memory map contains three groups of registers:
All registers except the channel interrupt status register (CISR) must be read or written
by means of half-word (16-bit) or word (32-bit) accesses. The address space of the
TPU3 memory map occupies 512 bytes. Unused registers within the 512-byte address
space return zeros when read.
