Figure 5-24 IDE Master/Slave Handshake Signals Connection
5.6.2.2 UDMA Support
Some SOM-Express modules support UDMA 33 data transfer mode. If an advanced
IDE data transfer mode such as UDMA 66 is required, it requires a special 80-
conductor IDE cable for signal integrity.
For UDMA 66 support, it is recommended the IDE bus and total cable length of
carrier board do not exceed 13 inches.

All necessary pull up/down resistors are implemented on the SOM module and do
not need to be implemented on the carrier board.
