All TMP512/13 registers are 16-bit registers. 16-bit register data are sent in two 8-bit bytes via the two-wire

interface.

Bit Descriptions

RST: Reset Bit

Bit 15 Setting this bit to '1' generates a system reset that is the same as power-on reset. Resets all registers to default

values; this bit self-clears.

ONE-SHOT One-Shot Bit

Bit 14 Setting this bit to '1' generates a one-shot command.

BRNG: Bus Voltage Range

Bit 13 0 = 16V FSR

1 = 32V FSR (default value)

PG: PGA (Shunt Voltage Only)

Bits 12, 11 Sets PGA gain and range. Note that the PGA defaults to ÷8 (320mV range). Table 4 shows the gain and range for

the various product gain settings.
