b) Host system that do not support Ultra DMA modes greater than mode 2 shall not connect
to the PDIAG-:CBLID- signal.
c) Host system that do support Ultra DMA modes greater than mode 2 shall either connect
directly to the device without using a cable assembly, or determine the cable assembly
type. Determining the cable assembly type may be done either by the host sensing the
condition of the PDIAG-:CBLID- signal (see Figure 3.11), or by relying on information
from the device (see Figure 3.12). Hosts that rely on information from the device shall
have a 0.047 F capacitor connected from the PDIAG-:CBLID- signal to ground. The
tolerance on this capacitor shall be 20% or less.
