13.2.4 Power-Class Programming

The S2_PC0, S1_PC1, and S0_PC2 terminals can be used in some port speed/mode selections to set the default value of the power-class indicated in the pwr field (bits 21–23) of the transmitted self-ID packet. Descriptions of the various power-classes are given in Table 13-9. The default power-class value is loaded following a hardware reset, but is overridden by any value subsequently loaded into the Pwr_Class field in register 4.

Table 13-9 Power-Class Descriptions
PC0–PC2DESCRIPTION
000Node does not need power and does not repeat power.
001Node is self-powered and provides a minimum of 15 W to the bus.
010Node is self-powered and provides a minimum of 30 W to the bus.
011Node is self-powered and provides a minimum of 45 W to the bus.
100Node can be powered from the bus and is using up to 3 W; no additional power is needed to enable the link. The node can also provide power to the bus. The amount of bus power that it provides can be found in the configuration ROM.
101Reserved for future standardization.
110Node is powered from the bus and uses up to 3 W. An additional 3 W is needed to enable the link.
111Node is powered from the bus and uses up to 3 W. An additional 7 W is needed to enable the link.

A. The IEEE Std 1394-1995 calls for a 250-pF capacitor, which is a nonstandard component value. A 270-pF capacitor is recommended.
