305 / 555 page ![]() Revision 0.8 305 www.national.com DIVIL Register Descriptions (Continued) 32 LB_ADAP_BAD_ FLAG LBus Adapter Bad Flag. If high, records that an ERR was generated due to the GeodeLink Adapter detected an error at the GeodeLink interface (e.g., packet type not supported). LB_ADAP_BAD_EN (bit 0) must be high to generate ERR and set flag. Write 1 to clear; writing 0 has no effect. 31:17 RSVD Reserved. Reads return 0. Writes have no effect. 16 LPC_EXCP_EN LPC Exception Enable. Write 1 to enable EXCEP bit in response packet for LPC address errors. 15 SHTDWN_ ERR_EN Shutdown Error Enable. Write 1 to enable SHTDWN_ERR_FLAG (bit 47) and to allow a Shutdown cycle to generate an ERR. 14 NAND_DIST_ ERR_EN NAND Distract Error Enable. Write 1 to enable NAND_DIST_ERR_FLAG (bit 46) and to allow a NAND distract error to generate an ERR. 13 RSVD Reserved. Reads return 0. Writes have no effect. 12 DMA_DMA_ ERR_EN 8237 DMA Error Enable. Write 1 to enable DMA_DMA_ERR_FLAG (bit 44) and to allow an access on the 8237s during DMA to generate an ERR. 11 LPC_DMA_ ERR_EN LPC DMA Error Enable. Write 1 to enable LPC_DMA_ERR_FLAG (bit 43) and to allow an LPC access during DMA an LPC access during DMA to generate an ERR. 10 RSVD Reserved. Reads return 0. Writes have no effect. 9UART2_DMA_ ERR_EN UART2 DMA Error Enable. Write 1 to enable UART2_DMA_ERR_FLAG (bit 41) and to allow UART2 accesses during DMA to generate an ERR. 8UART1_DMA _ERR_EN UART1 DMA Error Enable. Write 1 to enable UART1_DMA_ERR_FLAG (bit 40) and to allow UART1 accesses during DMA to generate an ERR. 7:6 RSVD Reserved. Reads return 0. Writes have no effect. 5 LPC_MAST_ ERR_EN LPC Master Error Enable. Write 1 to enable LPC_MAST_ERR_FLAG (bit 37) and to allow Master <=> GeodeLink Adapter transactions to generate an ERR. 4LPC_SLV_ ERR_EN LPC Slave Error Enable. Write 1 to enable LPC_SLV_ERR_FLAG (bit 36) and to allow Slave <=> GeodeLink Adapter transactions to generate an ERR. 3 MAST_RESP_ EXCEP_EN Master Response Exception Enable. Write 1 to enable MAST_RESP_EXCEP_FLAG (bit 35) and to allow when the GeodeLink Adapter detects the EXCEP bit set in a local bus master response packet to generate an ERR. 2 REPEAT_SSMI_ ERR_EN Repeat SSMI Error Enable. Write 1 to enable REPEAT_SSMI_ERR_FLAG (bit 34) and to allow when a second SSMI occurs on an address before the first was cleared to generate an ERR. 1 DECODE_ ERR_EN Decode Error Enable. Write 1 to enable FLAG bits [54:52] and to allow when one or more devices are decoded to the same address during the address decode cycle to generate an ERR. 0 LB_ADAP_ BAD_EN LBus Adapter Bad Enable. Write 1 to enable LB_ADAP_BAD_FLAG (bit 32) and to allow when the GeodeLink Adapter detects an error at the GeodeLink interface to gen- erate an ERR.
