FIFO operation (continued)
power down
Writing 8000h to the device puts the device into a software power-down state. For a hardware power down, the
dedicated PWDN pin provides another way to power down the device asynchronously. These two power-down
modes power down the entire device including the built-in reference to save power. It requires 20 ms to resume
from either a software or hardware power down.
Auto power down mode is always enabled. This mode maintains the built-in reference if an internal reference
is used, so resumption is fast enough to be used between cycles.
The configuration register is not affected by any of the power down modes but the sweep operation sequence
has to be started over again. All FIFO contents are cleared by the power-down modes.
power up and initialization
Initialization requires:
1.
Determine processor type by writing A000h to the TLC2554/58
2.
Configure the device
The first conversion after power up or resuming from power down is not valid.

Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: When binary output format is used, analog input voltages greater than that applied to REFP convert as all ones (111111111111), while
input voltages less than that applied to REFM convert as all zeros (000000000000). The device is functional with reference down to
2 V (VREFP – VREFM –1); however, the electrical specifications are no longer applicable.
