Detailed Description

DAC161S997 Status Register.

This union represents the contents of the DAC161S997's STATUS register. It provides access to individual status bits as well as the raw register value.

Field Documentation

◆ [struct]

struct { ... } dac161s997_status

Bit-field access to the status register.

◆ current_loop_status

bool dac161s997_status::current_loop_status

Loop error status (real-time).

This flag is set to true when the loop supply voltage is too low to support the programmed output current.

◆ dac_resolution

uint8_t dac161s997_status::dac_resolution

DAC resolution.

Always returns 0x7.

◆ error_level_pin_state

bool dac161s997_status::error_level_pin_state

ERR_LVL pin state.

◆ frame_status

bool dac161s997_status::frame_status

Frame error.

A frame error is caused by an incorrect number of clocks during a register write. A register write without an integer multiple of 24 clock cycles will cause a frame error.

◆ loop_status

bool dac161s997_status::loop_status

Loop error status (latched).

Similar to current_loop_status, except that this flag stays set until the status register is read or the device is reset.

◆ raw

uint8_t dac161s997_status::raw

Raw 8-bit value of the status register.

◆ spi_timeout_error

bool dac161s997_status::spi_timeout_error

SPI timeout error.

The default timeout is 100 ms. If this error occurs, it is cleared with a properly formatted write command to a valid address.
