ONE-SHOT CONVERSION
The One-Shot register is used to initiate a round of conversions and comparisons when the device is in standby
mode, after which the device returns to standby. This is not a data register and it is the write operation that
causes the one-shot conversion. The data written to this address is irrelevant and is not stored. A zero will
always be read from this register. All the channels that are enabled in the Channel Enable Register will be
converted once and the TCRIT1, TCRIT2 and TCRIT3 pins will reflect the comparison results based on this
round of conversion results of the channels that are not masked.
LM95234 Registers
Command register selects which registers will be read from or written to. Data for this register should be
transmitted during the Command Byte of the SMBus write communication.
