Register Definition
2.2.1
Mode Register
The Mode Register is used to define the specific mode of operation of the Mobile-RAM. This definition includes the selection
of a burst length (bits A0-A2), a burst type (bit A3), a CAS latency (bits A4-A6), and a write burst mode (bit A9). The Mode
Register is programmed via the MODE REGISTER SET command (with BA0 = 0 and BA1 = 0) and will retain the stored
information until it is programmed again or the device loses power.
The Mode Register must be loaded when all banks are idle, and the controller must wait the specified time before initiating any
subsequent operation. Violating either of these requirements results in unspecified operation.
Reserved states should not be used, as unknown operation or incompatibility with future versions may result.
