sequence is complete, the user
must set STOP in CSR0. Then the
user may write to CSR47 and then
set STRT in CSR0. In this way, the
default value of 0000 in CSR47 will
be overwritten with the desired user
value.
If the user does NOT use the
standard initialization procedure
(standard implies use of an in-
itialization block in memory and
setting the INIT bit of CSR0), but
instead, chooses to write directly to
each of the registers that are
involved in the INIT operation, then it
is imperative that the user also write
0000 0000 to CSR47 as part of the
alternative initialization sequence.
Read/write accessible only when
STOP bit is set.
