bits 0–7 = “n” such that 2n HEX value represents the number of read-
page bytes. See offset 28h for device word width to determine page-
mode data output width. 00h indicates no read page buffer.

HEX value represents the maximum
number of continuous synchronous burst 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 until 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 Bits 0-2 if the device is configured for
its maximum word width. See offset 1Fh for word width to determine
the burst data output width.
