- Starting Address: 30000
Update a voltage output on a connected LJTick-DAC accessory. Even TDAC# = DACA, Odd TDAC# = DACB. For instance, if LJTick-DAC accessory is connected to FIO2/FIO3 block on main device, TDAC2 corresponds with DACA, and TDAC3 corresponds with DACB.

TDAC_SERIAL_NUMBER
- Address: 55200
Returns the serial number of an LJTick-DAC, and forces a re-read of the calibration constants. Which LJTDAC is determined by the last write to TDAC# ... whether it was successful or not.

TDAC_SPEED_THROTTLE
- Address: 55202
Sets the I2C clock speed that will be used when communicating with the TDAC. Default value is 65516. See I2C_SPEED_THROTTLE for more detail.
