Partition Configuration. In the Non-Enhanced mode, Ayama 10000 is internally
divided into 32/16/8 partitions corresponding to CYNSE10512/256/128 respec-
tively. Each two bits configures one partition as encoded below:
00: 8K × 72
01: 4K × 144
10: 2K × 288
11: Disabled (Does not reduce power consumption in a Search operation)
Bit[1:0] configures the first partition, Bit[3:2] configures the second partition and so
on. Bit [15:0] of this register is aliased in Bit[24:9] of the Command register. Modifi-
cation to Bit[15:0] of this field will affect the CFGA field in the Command register
and vice versa.
