9.10.4 Working with 16/32-Bit Systems
mDOC H3 uses a 16-bit data bus and supports 16-bit data access by default. However, it can be
configured to support 32-bit data access mode. This section describes the connections required
for each mode.
The default of the DOC driver for mDOC H3 is set to work in 16-bit mode. It must be specially
configured to support 32-bit mode. Please see DOC Driver or TrueFFS 7.1 documentation for
further details.
Note: The mDOC H3 data bus must be connected to the Least Significant Bits (LSB) of the
16-Bit (Word) Data Access Mode
The mDOC H3 is 16 bit wide device. All accesses to and from the device are 16 bit wide.
mDOC H3 address lines should be connected to system host address lines, as depicted in Figure
14.
mDOC H3 A0 line should be connected either to system host SA0 address line, or to VSS.
32-Bit (Double Word) Data Access Mode
In a 32-bit bus system that cannot execute word-aligned accesses, the system address lines SA0
and SA1 are always 0. Consecutive double words (32-bit words) are differentiated by SA2
toggling. Therefore, in 32-bit systems that support only 32-bit data access cycles, mDOC H3
signal A1 is connected to the first system address bit that toggles; i.e., SA2.
mDOC H3 address lines should be connected to system host address lines, as depicted in Figure
16.
mDOC H3 A0 line should be connected either to system host SA1 address line, or to VSS
