The device can be programmed to respond in asynchronous mode with the following settings:
In asynchronous mode, the device transmits data at a fixed rate (t
The device can be programmed to respond in Simultaneous Sampling Mode by setting the TRANS_MD[1:0] bits to “Normal

Normal Mode
• TRANS_MD[1:0] = ‘00’ (“Normal Mode”)
• ASYNC = ‘1’ in the DEVCFG6 Register
• TIMESLOTA[9:0] = 0x000 in the DEVCFG3 and DEVCFG4 registers
