 * PCI bus controller parity detection configuration parameter 
 *
 * NOTE: PCI bus controller can be an Initiator or Target of PCI bus
 * transactions  but there is one single parity bit that controls the
 * parity detection on both the interfaces.  Since, it is possible to 
 * differentiate between the Initiator and Target interfaces by reading
 * some other bits in the registers, the software choose to implement 
 * the enabling or disabling of parity error detection. The main module
 * will implement these configuration and filtering capabilities but 
 * for the parity enabler sub-module it is simply enable or disable of 
 * parity detection.
