5.8 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 .
