Address Range

The following correlation must exist between the

"Link Registers" on page 2-47).
= 2 (internal memory) ⇒ address is in internal memory range,

TY
and not in the registers (see "Internal Address Space" on page 2-6).
= 4 (external memory) ⇒ address is in external memory range

TY
(address31–22 non-zero). It can be in host, external memory or
multiprocessing space.
!
When a link DMA channel (transmit or receive channel) becomes
active, if the transmit buffer is empty (for transmit channel) or if
the receive buffer is not empty (for receive channel), a DMA
request is immediately issued.
