Figure 9-16. Memory Error Disable Register (ERR_DISABLE)

Table 9-20 describes the ERR_DISABLE fields.

9.4.1.16 Memory Error Interrupt Enable (ERR_INT_EN)

The memory error interrupt enable register, shown in Figure 9-17, enables ECC interrupts or

memory select error interrupts. When an enabled interrupt condition occurs, the internal int signal

is asserted to the programmable interrupt controller (PIC).

MBED Multiple-bit ECC error disable

0 Multiple-bit ECC errors are detected if DDR_SDRAM_CFG[ECC_EN] is set. They are reported if

ERR_INT_EN[MBEE] is set. Note that uncorrectable read errors cause the assertion of core_fault_in,

which causes the core to generate a machine check interrupt, unless it is disabled (by clearing

HID1[RFXE]). If RFXE is zero and this error occurs, MBED must be zero and ERR_INT_EN[MBEE]

and ECC_EN must be one to ensure that an interrupt is generated.

1 Multiple-bit ECC errors are not detected or reported.

SBED Single-bit ECC error disable

0 Single-bit ECC errors are enabled.

1 Single-bit ECC errors are disabled.

MSED Memory select error disable
