Field
Description
SAD
Shadow Address. The SAD bit qualifies the address captured during an ECC Event Error, Single Bit Correction,
or State Machine operation.
The SAD register is not writable.
0 Address Captured is from Main Array Space.
1 Address Captured is from Shadow Array Space.
ADDR[20:3]
Address. The ADR register provides the first failing address in the event of ECC event error (MCR[EER] set),
single bit correction (MCR[SBC] set), as well as providing the address of a failure that may have occurred in a
state machine operation (MCR[PEG] cleared). ECC event errors take priority over single bit corrections, which
take priority over state machine errors. This is especially valuable in the event of a RWW operation, where the
read senses an ECC error or single bit correction, and the state machine fails simultaneously. This address is
always a Double Word address that selects 64 bits.
The ADR register is writable, and can be used in the UTest ECC Logic Check. If the ECC logic check is enabled
(UT0[EIE] = 1) then the ADR register will not update for ECC event error, single bit correction, or state machine
errors.
If MCR[EER] or MCR[SBC] are set, the ADR register is locked from writing. MCR[PEG] does not affect the
writability of the ADR register.
21.3.2.8 Platform Flash Configuration Registers (PFCRP0 and PFCRP1)
The PFLASH configuration register for port 0 (PFCRP0) is used to specify operation of port p0 of the flash
memory module. This register also has two bits (ARB and PRI) to control arbitration between the p0/p1
ports.
The PFLASH configuration register for port 1 (PFCRP1) is used to specify operation of port p1 of the flash
memory module.
The PFCRPn registers are shown in Figure 21-10, Figure 21-11, and Table 21-11.
Master ID mapping can be found in Table 9-1.
