44 / 49 page ![]() AD5413 Data Sheet Rev. 0 | Page 44 of 49 Bits Bit Name Description Reset Access 2 FREQ_MON_EN Internal Frequency Monitor on MCLK Enable. 0x1 R/W 0: disable. 1: enable (default). 1 RESERVED Reserved. 0x0 R/W 0 SPI_CRC_EN SPI CRC Function Enable. 0x1 R/W 0: disable. 1: enable (default). FAULT Pin Configuration Register Address: 0x12, Reset: 0x120000, Name: FAULT_PIN_CONFIG The FAULT_PIN_CONFIG register is used to mask particular fault bits from the FAULT pin, if so desired. Table 34. Bit Descriptions for FAULT_PIN_CONFIG Bits Bit Name Description Reset Access 21 FAULT_PIN_STATUS This bit reflects the current status of the FAULT pin. 0x0 R [20:16] REGISTER_ADDRESS Register Address. 0x0 R 15 INVALID_SPI_ACCESS_ERR If this bit is set, do not map the invalid SPI access fault flag to the FAULT pin. 0x0 R/W 14 RESERVED Reserved. 0x0 R/W 13 RESERVED Reserved. 0x0 R/W 12 INVERSE_DAC_CHECK_ERR If this bit is set, do not map the inverse DAC check error flag to the FAULT pin. 0x0 R/W 11 RESERVED Reserved. 0x0 R/W 10 OSCILLATOR_STOP_DETECT If this bit is set, do not map the oscillator stop detect fault to the FAULT pin. 0x0 R/W 9 DAC_LATCH_MON_ERR If this bit is set, do not map the DAC latch monitor error flag to the FAULT pin. 0x0 R/W 8 RESERVED Reserved. 0x0 R/W 7 SLIPBIT_ERR If this bit is set, do not map the slip bit error flag to the FAULT pin. 0x0 R/W 6 SPI_CRC_ERR If this bit is set, do not map the SPI CRC error flag to the FAULT pin. 0x0 R/W [5:4] RESERVED Reserved. 0x0 R/W 3 IOUT_OC_ERR If this bit is set, do not map the current output open-circuit error flag to the FAULT pin. 0x0 R/W 2 VOUT_SC_ERR If this bit is set, do not map the voltage output short-circuit error flag to the FAULT pin. 0x0 R/W 1 RESERVED Reserved. 0x0 R/W 0 DIE_TEMP_ERR If this bit is set, do not map the die temperature error flag to the FAULT pin. 0x0 R/W Two-Stage Readback Select Register Address: 0x13, Reset: 0x130000, Name: TWO_STAGE_READBACK_SELECT The TWO_STAGE_READBACK_SELECT register selects the address of the register required for a two-stage readback operation. The address of the register selected for readback is stored in Bits[4:0]. Table 35. Bit Descriptions for TWO_STAGE_READBACK_SELECT Bits Bit Name Description Reset Access 21 FAULT_PIN_STATUS This bit reflects the current status of the FAULT pin. 0x0 R [20:16] REGISTER_ADDRESS Register Address. 0x0 R [15:7] RESERVED Reserved. 0x0 R [6:5] READBACK_MODE SPI Readback Mode Control Bits. 0x0 R/W 0: two-stage SPI readback mode (default). 01: autostatus readback mode. The status register contents are shifted out on SDO for each SPI frame. 10: shared SYNC autostatus readback mode. This mode allows the use of a shared SYNC line on multiple devices (distinguished using the hardware address pins). After each valid write to a device, a flag is set. This mode behaves similarly to the normal autostatus readback mode, except the device does not output the status register contents on SDO as SYNC goes low, unless the internal flag is set (that is, the previous SPI write is valid). |
