Block n Enable Status Register (BLKn_EN_STAT)
SRIO Registers
There are nine of these registers, one for each of nine logical blocks in the peripheral. The registers and
the blocks they support are listed in
Table 48
. The general form for a block n enable status register
(BLKn_EN_STAT) is shown in
Figure 69
and described in
Table 49
. For additional programming
information, see
Section 2.3.10
.
