REGISTER DETAILS
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.
