EMI_BWR_WRLn is the data write strobe, and the output on pin EMI_RDn is the data read
strobe.

8-bit non-multiplexed data mode
bits of address are output on ports 7 and 9. The output signal on pin EMI_BWR_BWLn
is the data write strobe and the output on pin EMI_RDn is the data read strobe.
Burst Mode Support (LFBGA package only): The EMI bus supports synchronized
burst read and write bus cycle in multiplexed and non-multiplexed mode. The additional
EMI signals in the LFBGA package that support the burst mode are:
–
–
–
–
–
By defining the bus parameters such as burst length, burst type, read and write timings
in the EMI control registers, the EMI bus is able to interface to standard burst memory
devices. The burst timing specification and waveform will be provided in the next data
sheet release
EMI_BCLK -the bus clock output. The EMI_BCLK has the same frequency or half
of that of the HCLK and can be disabled by the user
EMI_WAITn - the not ready or wait input signal for synchronous access
EMI_BAAn - burst address advance or burst enable signal
EMI_WEn - write enable signal
EMI_UBn, EMI_LBn - upper byte and lower byte enable signals. These two signals
share the same pins as the EMI_WRLn and EMI_WRHn and are user configurable
through the EMI register.
