DIVIL Register Descriptions (Continued)

MEM_LBAR_

DECODE_

ERR_FLAG

Memory LBAR Decode Error Flag. If high, records that an ERR was generated due to

a collision between one memory LBAR and another memory LBAR hit. In this case, NO

chip select is generated and DECODE_ERR_FLAG (bit 33) is asserted.

DECODE_ERR_EN (bit 1) must be high to generate ERR and set flag. Write 1 to clear;

writing 0 has no effect.

IO_LBAR_

DECODE_ERR_

FLAG

I/O LBAR Decode Error Flag. If high, records that an ERR was generated due to a col-

lision between one I/O LBAR and another I/O LBAR hit. In this case, NO chip select is

generated and DECODE_ERR_FLAG (bit 33) is asserted.DECODE_ERR_EN (bit 1)

must be high to generate ERR and set flag. Write 1 to clear; writing 0 has no effect.

51:48

RSVD

Reserved. Reads return 0. Writes have no effect.

SHTDWN_

ERR_FLAG

Shutdown Error Flag. If high, records that an ERR was generated due to a Shutdown

cycle occurrence. SHTDWN_ERR_EN (bit 15) must be high to generate ERR and set

flag. Write 1 to clear; writing 0 has no effect.

NAND_DIST_

ERR_FLAG

NAND Distract Error Flag. If high, records that an ERR was generated due to a NAND

distract error. NAND_DIST_ERR_EN (bit 14) must be high to generate ERR and set

flag. Write 1 to clear; writing 0 has no effect.

RSVD

Reserved. Reads return 0. Writes have no effect.

DMA_DMA_

ERR_FLAG

8237 DMA Error Flag. If high, records that an ERR was generated due to an access on

the 8237s during DMA. DMA_DMA_ERR_EN (bit 12) must be high to generate ERR

and set flag. Write 1 to clear; writing 0 has no effect.

LPC_DMA_

ERR_FLAG

LPC DMA Error Flag. If high, records that an ERR was generated due to an LPC

access during DMA. LPC_DMA_ERR_EN (bit 11) must be high to generate ERR and

set flag. Write 1 to clear; writing 0 has no effect.

RSVD

Reserved. Reads return 0. Writes have no effect.

UART2_DMA_

ERR_FLAG

UART2 DMA Error Flag. If high, records that an ERR was generated due to a UART2

access during DMA. UART2_DMA_ERR_EN (bit 9) must be high to generate ERR and

set flag. Write 1 to clear; writing 0 has no effect.

UART1_DMA_

ERR_FLAG

UART1 DMA Error Flag. If high, records that an ERR was generated due to a UART1

access during DMA. UART1_DMA_ERR_EN (bit 8) must be high to generate ERR and

set flag. Write 1 to clear; writing 0 has no effect.

39:38

RSVD

Reserved. Reads return 0. Writes have no effect.

LPC_MAST_

ERR_FLAG

LPC Master Error Flag. If high, records that an ERR was generated on the LPC due to

a Master <=> GeodeLink Adapter transaction. LPC_MAST_ERR_EN (bit 5) must be

high to generate ERR and set flag. Write 1 to clear; writing 0 has no effect.

LPC_SLV_

ERR_FLAG

LPC Slave Error Flag. If high, records that an ERR was generated on the LPC due to

a Slave <=> GeodeLink Adapter transaction. LPC_SLV_ERR_EN (bit 4) must be high

to generate ERR and set flag. Write 1 to clear; writing 0 has no effect.

MAST_RESP_

EXCEP_FLAG

Master Response Exception Flag. If high, records that an ERR was generated due to

the GeodeLink Adapter detecting the EXCEP bit set in a local bus master response

packet. MAST_RESP_EXCP_EN (bit 3) must be high to generate ERR and set flag.

Write 1 to clear; writing 0 has no effect.

REPEAT_SSMI_

ERR_FLAG

Repeat SSMI Error Flag. If high, records that an ERR was generated due to a second

SSMI occurring on an address before the first was cleared. REPEAT_SSMI_ERR_EN

(bit 2) must be high to generate ERR and set flag. Write 1 to clear; writing 0 has no

effect.

DECODE_ERR_

FLAG

Decode Error Flag. If high, records that an ERR was generated during the address

decode cycle due to one or more devices being decoded to the same address. Bits

[54:52] record further information about this type of error. DECODE_ERR_EN (bit 1)

must be high to generate ERR and set flag. Write 1 to clear; writing 0 has no effect.
