Exit Sleep Mode (WAKE)
The Exit Sleep Mode (WAKE) command turns on internal MRAM power regulators to allow normal operation.
The WAKE command is entered by driving CS low, sending the command code, and then driving CS high.
The memory returns to standby mode after tRDP. The CS pin must remain high until the tRDP period is over.
WAKE must be executed after sleep mode entry and prior to any other command.
