• 1 - Digital redundancy check fails.

Selftest Fault

Input

Binary

0

Forces a self test fault in response to the CVST, AXST, and STATST commands.

• 0 - Device passes the self test and the MUXFAIL bit is set to 0.

• 1 - Device fails the self test and the MUXFAIL bit is set to 1.

Vref2

Input

Decimal

V

0

Emulates the V_REF2 pin of a real device.

Vreg

Input

Decimal

Sum of Cells

Input

Decimal

V

0

Emulates the Sum of All Cells Measurement on the device, in degrees Celsius. The Sum of All Cells is subsequently used to calculate the SC value stored in Status Register Group A.

Cell Measurement x

Input

Decimal

V

0

Emulates the cell voltage measurement of Cell x. This measurement is taken between pin Cx and pin C(x-1) on a real device.

GPIO x

Input

Decimal

V

0

Emulates pins GPIO1 through GPIO5 of a real device.

Open Wire GPIOx

Input

Binary

0

Emulates an open wire on a GPIO line of the emulated device.

• 0 - Uninterrupted connection at pin GPIOx.

• 1 - Open wire at pin GPIOx.

Open Wire Cx

Input

Binary

0

Emulates an open wire between the external cells. This open wire condition can be detected using the ADOW command.

• 0 - Uninterrupted connection at pin Cx.

• 1 - Open wire at pin Cx.

STCOMM Reply Command

Input

Hexadecimal

0

When the STCOMM command is received from the SPI Master, the value of this channel is written to the COMM register of the emulated device. Map the command communication interface of an external device model, acting as an I²C or SPI slave, to this input channel.

To set the Default Value of this channel in the system definition, convert it to decimal notation. See How to Manage Hexadecimal and Binary Data in VeriStand Channels for more information.

STCOMM Reply Data

Input

Hexadecimal

0

When the STCOMM command is received from the SPI Master, the value of this channel is written to the COMM register of the emulated device. Map the data communication interface of an external device model, acting as an I²C or SPI slave, to this input channel.

To set the Default Value of this channel in the system definition, convert it to decimal notation. See How to Manage Hexadecimal and Binary Data in VeriStand Channels for more information.

Last Command Received

Output

Hexadecimal

0

Outputs the last command received from the SPI Master.

Command CRC Check

Output

Binary

0

Binary flag indicating a Command CRC mismatch in the last transmission received from the SPI Master.

• 0 - No CRC mismatch detected.

• 1 - CRC mismatch detected.

Data CRC Check

Output

Binary

0

Binary flag indicating a Data CRC mismatch in the last transmission received from the SPI Master.
