SLUSBX9I March 2014 – July 2019 TPS23861
Command = 17h with 1 Data Byte, Read/Write
|RESET or POR VALUE||1||0||0||0||Reserved||Reserved||Reserved||0|
INTEN:INT pin enable bit. Writing a 1 permits any bit of the Interrupt Register to activate the INT output.
Activating INTEN has no impact on the Event Registers.
1 = Any enabled bit of the Interrupt register can activate the INT output.
0 = INT output cannot be activated.
Reserved: Bits R17, R17 and R17 are reserved for future use. Undesirable behavior may result if the value of these bits are changed from the reset value.
MAINS: Detection Voltage Measurement Duration Bit. Set or clear this bit to correspond to the mains frequency local to where the TPS23861 is being used in a system. The A/D converter will perform 16 conversions during the detection cycle. The results of these 16 conversions are averaged resulting in a total acquisition time equal to one cycle of the mains frequency. This technique greatly reduces mains-induced interference in the detection cycle measurement.
1 = Convert port voltage during detection at a rate of 960 A/D conversions per second. This corresponds to 16 conversions during one period of 60-Hz mains frequency.
0 = Convert port voltage during detection at a rate of 800 A/D conversions per second. This corresponds to 16 conversions during one period of 50-Hz mains frequency.
M250: Current-sense-resistor-selection bit. Setting this bit directs the TPS23861 to use ICUT and classification look-up tables corresponding to a 250-mΩ current-sense resistor.
1 = Set this bit if a 250-mΩ current-sense resistor is used as a current-sense resistor.
0 = Clear this bit if a 255-mΩ current-sense resistor is used as a current-sense resistor.
