REGISTER INFORMATION
The TPS2480/81 uses a bank of registers for holding configuration settings, measurement results,
maximum/minimum limits, and status information. Table 4 summarizes the TPS2480/81 registers; illustrates
registers.
Register contents are updated 4 ms after completion of the write command. Therefore, a 4-ms delay is required
between completion of a write to a given register and a subsequent read of that register (without changing the
pointer) when using SCL frequencies in excess of 1 MHz.

Type: R = Read-Only, R/W = Read/Write.
(2)
The Power Register and Current Register default to '0' because the Calibration Register defaults to '0', yielding a zero current value until
the Calibration Register is programmed.
