Read Configuration Register (RCR)(Easy BGA)
The RCR is a 16-bit read/write register used to select the read mode (synchronous or
asynchronous), and to configure synchronous burst characteristics of the device. To
modify RCR settings, use the Configure Read Configuration Register command (see
Section 6.2, “Device Command Bus Cycles” on page
RCR contents can be examined using the Read Device Identifier command, and then
reading from offset 0x05 (see
Upon power-up or exit from reset, the RCR defaults to asynchronous mode.
The RCR is shown in
