REGISTER INFORMATION
The TMP512/13 uses a bank of registers for holding the write command. Therefore, a 4μs delay is
configuration settings, measurement results, required between the completion of a write to a given
maximum/minimum limits, and status information. register and a subsequent read of that register
Table 3 summarizes the TMP512/13 registers. (without changing the pointer) when using SCL
Register contents are updated 4μs after completion of frequencies in excess of 1MHz.

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