Offset Data
Description
Page-mode read capability
bits 0-7 n’ such that 2n HEX value represents the number of
read-page bytes. See offset 0028h for device word width to
determine page-mode data output width.

Number of synchronous mode read configuration fields that
follow.
Synchronous mode read capability configuration 1
bit 3-7 Reserved
bit 0-2 n’ such that 2n+1 HEX value represents the
maximum number of 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 0028h for word width to determine the burst data
output width.
