8.4.8 GPO Dependencies

GPIOs can be configured as outputs that are based on Boolean combinations of up to two ANDs, all ORed together (Figure 15). Inputs to the logic blocks can include the first 8 defined GPOs, GPIs and rail-status flags. One rail status type is selectable as an input for each AND gate in a Boolean block. For a selected rail status, the status flags of all active rails can be included as inputs to the AND gate. _LATCH rail-status types stay asserted until cleared by a MFR PMBus command or by a specially configured GPI pin. The different rail-status types are shown in Table 4. See the UCD90xxx Sequencer and System Health Controller PMBus Command Reference for complete definitions of rail-status types. The GPO response can be configured to have a delayed assertion or deassertion.
