DIGITAL ERROR MASK REGISTER (DIGITAL_ERR_DIS) DETAILS

The DIGITAL_ERR_DIS register can be used to mask individual error flags in the DIGITAL_ERR register. Setting bits in the

DIGITAL_ERR_DIS register to 1 disables the error flag.

Bit 6, CAL_BUSY_DIS—Disable Calibration Busy Error

Flag

This bit disables the CAL_BUSY error flag.

Bit 5, SPI_CRC_ERR_DIS—Disable SPI CRC Error Flag

When SPI_CRC_ERR_DIS is cleared to 0, the ADA4254 expects

an additional checksum byte with write commands and transmits

an extra checksum byte with read commands. By default, SPI_

CRC_ERR_DIS is set to 1 and this functionality is disabled.

After enabling CRC, a manual check can be performed to

ensure that the CRC configuration command was properly

communicated. If the CRC is used, it is recommended to

configure the CRC before other registers so that all subsequent

communication receives the CRC.

Bit 4, SPI_RW_ERR_DIS—Disable SPI Read/Write Error

Flag

This bit disables the SPI_RW_ERR error flag.

Bit 3, SPI_SCLK_CNT_ERR_DIS—Disable SPI SCLK Count

Error Flag

This bit disables the SPI_SCLK_CNT_ERR error flag.

Bit 2, M_CLK_CNT_ERR_DIS—Disable Master Clock

Count Output

When this bit is set to 0, the master clock is updated in the

M_CLK_CNT register. Setting this bit to 1 stops M_CLK_CNT

from incrementing.

Bit 1, MM_CRC_ERR_DIS—Disable Memory Map CRC

Error Flag

This bit disables the MEM_MAP_ERR error flag.

Bit 0, ROM_CRC_ERR_DIS—Disable ROM CRC Error Flag

This bit disables the ROM_CRC_ERR error flag.
