3-Wire Command Format
NT39016 uses the 3-wire serial port as communication interface for all the function and parameter setting.
3-Wire communication can be bi-directional controlled by the “R/W” bit in address field. NT39016 3-Wire engine
act as a “slave mode” for all the time, and will not issue any command to the 3-Wire bus itself.
Under read mode, 3-Wire engine will return the data during “Data phase”. The returned data should be latched at
the rising edge of SPCK by external controller. Data in the “Hi-Z phase” will be ignored by 3-Wire engine during
write operation, and should be ignored during read operation also. During read operation, external controller
should float SPDA pin under “Hi-Z phase” and “Data phase”.
Refer to the section of “3-Wire Timing Diagram” for the detail timing, please.
