32M Synchronous Burst CellularRAM
Functional Description
2.4
Bus Control Register
The Bus Control Register (BCR) specifies the interface configurations. For the various configuration options
please refer to the register description below. The Bus Control Register is programmed via the Control Register
Set command (with CRE = 1 and A19 = 1) and retains the stored information until it is reprogrammed or the device
loses power.
Please note that the BCR contents can only be set or changed when the CellularRAM is in idle state.
Note:Bit 9 must be set to “0” and bit 6 to “1” for proper operation.

Operation Mode
The CellularRAM supports three different interface access protocols,
the SRAM-type protocol with asynchronous read and write accesses
the NOR-FLASH-type protocol with synchronous read and asynchronous write
accesses
the FULL SYNCHRONOUS mode with synchronous read and synchronous write
accesses
Operating the device in synchronous mode maximizes bandwidth. The NOR-Flash
type mode is the recommended mode for legacy baseband systems which are not
able to run the synchronous write protocol.
The OPMODE bit defines whether the device is operating in synchronous (fully or
partially) mode or asynchronous mode.

FULL SYNCHRONOUS mode
read: synchronous burst mode
write: synchronous burst mode
The mode of write operation, NOR-FLASH or FULL SYNCHRONOUS, is adaptively
detected:
This is done by detecting a rising clock edge during ADV valid. If a rising clock edge
occurs within ADV valid, FULL SYNCHRONOUS write is detected. If there is no rising
clock edge then NOR FLASH write is detected. Please refer to
Figure 22

Page 40
for asynchronous write and to
Figure 25
on
Page 43
for synchronous write.

Latency Mode
The latency mode has to be adjusted to the desired burst frequency. Depending on
the programmed latency, driving 1

data output is delayed by the number of clock
cycles as specified in this field counting from the address valid strobe signal, ADV.
