PERR# Generation
Параметр, включающий/отключающий генерирование PERR# (PCI bus parity error) — сигнал ошибки в четности данных, передаваемых по шине PCI. Сигнал PERR# направляется на контролер немаскируемых прерываний (NMI).
PERR# является устойчивым сигналом трех состояний, используемым для сигнализации об обнаружении ошибки четности, связанной с фазой данных. Во время каждой фазы данных транзакции чтения целевой объект передает данные на шину AD. Таким образом, цель состоит в том, чтобы обеспечить правильную четность для инициатора по сигналу PAR, начинающемуся через один такт после подтверждения TRDY# (Target Ready). По завершении каждой фазы данных инициатор обязан зафиксировать содержимое AD (31: 0] и C/BE # [3: 0] и рассчитать ожидаемый паритет в течение тактового цикла, сразу после завершения фазы данных. Затем инициатор фиксирует бит четности, предоставленный целью, из сигнала PAR на следующем переднем фронте тактовых импульсов и сравнивает вычисленную и фактическую четность. Если происходит несовпадение, инициатор затем устанавливает PERR# в течение следующих тактовых импульсов (если это можно сделать с помощью единицы в бите ответа об ошибке четности в его регистре команд.) Утверждение PERR # откладывает завершение каждой фазы данных на два тактовых цикла PCI.
Иными словами, включение данной функции позволяет обнаруживать ошибки, возникающие при передаче данных по шине PCI.
Возможные варианты значений:
Disable — генерирование PERR# отключено
Enable — генерирование PERR# включено
