Turbo PMAC/PMAC2 Software Reference

Turbo PMAC Global I-Variables 116

If amplifier flags are specified separately using Ixx42, they must use the same type of ICs as does Ixx25,

those specified by bit 0 of Ixx24.

Bits 18 and 19 of Ixx24 specify whether the amplifier flags and the capture flags are connected directly to

Turbo PMAC circuitry, or interface to it through the MACRO ring as shown in the following table:

The following tables show the standard addresses that can be used for Ixx42.
