Description
Page-mode read capability
Value
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.

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 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.
