2. Bank Regions. There are two Bank Regions, 1 contains all the banks that are made up of main blocks only, 2 contains the banks
4Ah
that are made up of the parameter and main blocks.

continuous synchronous reads when the device is configured
for its maximum word width. A value of 07h indicates that the
device is capable of continuous linear bursts that will output
data until the internal burst counter reaches the end of the
device’s burstable address space. This field’s 3-bit value can
be written directly to the read configuration register bit 0-2 if
the device is configured for its maximum word width. See
offset 28h for word width to determine the burst data output
width.
