A RAM access interrupt in each channel indicates that
the pending RAM access request is serviced. For a
RAM access, the ADDRESS and DATA is transferred
from the SPI registers to the address and data buffers in
the appropriate channel. The RAM WRITE request is
logged. As for READ operations, the status of the
pending request is monitored by either polling the

RAMSTAT bit for the channel or enabling the RAM
access interrupt for the channel. By keeping the
address, data buffers, and RAMSTAT register on a per-
channel basis, RAM address accesses can be
scheduled for both channels without interface.
