Section 2 Signal Description
The 9S12UF32 has two package options, the first one is a full featured 100-pin package and the second
one in a low cost 64-pin package.
In the 100-pin option, three primary software selectable configurations are available for different end
applications.
• USB 2.0 to ATA and CF bridge
• USB 2.0 to ATA, SM, SD (MMC) and MS bridge
• USB 2.0 to CF, SM, SD (MMC) and MS bridge
Below table shows a summary of how the above configurations can be selected.

Specific Notes
When TIMER is enabled,
timer channel pins IOC[7:4]
will be available on PR[7:4]
if CA10E, CA9E, CA8E and
CA7E in CFSCR2 of CFHC
are set to 0.
When SCI is enabled, SCI
module pins TXD and RXD
will be available on PR[3:2]
if CA6E and CA5E in
CFSCR2 of CFHC are set to
0.
None
When TIMER is enabled,
timer channel pins IOC[7:4]
will be available on PR[7:4]
if CA10E, CA9E, CA8E and
CA7E in CFSCR2 of CFHC
are set to 0.
When SCI is enabled, SCI
module pins TXD and RXD
will be available on PR[3:2]
if CA6E and CA5E in
CFSCR2 of CFHC are set
to 0.
General Notes
If the pins are associated with a module which is not enabled, those pins can be served
as general purpose I/O at the voltage of the corresponding power supply rail.
In the 64-pin option, four primary software selectable configurations are available for different end
applications.
• USB 2.0 to ATA bridge with optional SDHC support
• USB 2.0 to SM, SD (MMC) and MS bridge
