Notes: When using a 44- pin IDE connector, pins 41 and 42 must be connected to VCC
and pins 43 and 44 must be connected to ground. All other pins are equivalent to a
40-pin IDE connector. Additionally, decoupling capacitors should be connected to the
VCC pins.
4.9.3 CF Connector
CompactFlash (CF) cards with DMA capability require that the two signals 'IDE_REQ'
and 'IDE_ACK#' are routed to the CF card socket on the COM Express carrier board.
If this is not done then some DMA capable CF cards may not work because they are
not designed for non DMA mode. For more information about this subject refer to the
datasheet of the CF card or contact your CF card manufacturer. If two CF cards are
used in master/slave mode on the same IDE channel, the signal 'CSEL#' of the CF
card socket that drives the slave CF card must be tied to ground. In master mode the
'CSEL#' signal must be left open. Figure 4-31 shows a circuitry implementing a CF
card socket that is DMA capable.
