EMI DACK mapping
For full details of the EMI bank address and bank type mappings refer to
ST40 Architecture Manual
Volume 2: Bus Interfaces.
Two DACK strobes are supported in this implementation and are mapped as follows:
q
DACK
[0]: asserted when a transfer from GPDMA channel[1] occurs to an EMI bank configured
as a MPX device,
q
DACK
[1]: asserted when a transfer from GPDMA channel[2] occurs to an EMI bank configured
as a MPX device.
4.6
EMI address pin mapping
The data width of a connected device is 8, 16 or 32 bits wide. The 16-bit bank must use EDQM3 as
address 1, the LSB address for the device and the 8-bit bank must use EDQM3 as address 1 and
EDQM
2 as address 0.
See the
ST40 System Architecture Manual, Volume 2: Bus Interfaces for details of setting the
device type and port size using the EMI configuration registers.
