5.4.7
Table 5-11 describes the Write Burst Address register fields. These must be programmed before issuing a Burst-Write operation.
Table 5-11. Write Burst Register Description
5.4.8
The NFA register is used only when the device operates in the Non-Enhanced mode. The NFA register’s Index field (Table 5-12)
holds the address of the highest priority free entry in the table. When the table is full, the Index field will be set to all 1s. When all
entries in the device is full, the Ayama 10000A will assert FULO[1:0] to “11”.

Address. This field is used to identify the starting address of the data or
mask array in a Burst-Write operation. The NSE will automatically
increment the value by one after each successive Write of the data or mask
array. It must be reinitialized before the next Burst-Write operation. N = 17
for CYNSE10512A, 16 for CYNSE10256A, 15 for CYNSE10128A.
Reserved. M = 18 for CYNSE10512A, 17 for CYNSE10256A, 16 for
CYNSE10128A.
Length of Burst Access. The device provides the capability to Write from
4 to 511 locations in a single burst. The NSE automatically decrements the
value by one after each successive writing of the data or mask array. It must
be reinitialized before the next Burst-Write operation.
Reserved.
Index. The address index of the next-free entry location. N = 17 for
