Table 14. TWI Commands Descriptions
Command
Descriptions
Implemented by pulling the DATA pin low for 32 clock cycles and clocking in 0x8D00, 48 clock cycles in total.
TWI_RST
It only resets the TWI circuit to make sure it functions correctly. The DATA pin cannot detect the
Rising/Falling edge to trigger transmission after this command, until the TWI_OFF command is issued.
Notes:
1. Please ensure the DATA pin is firmly pulled low during the first 32 clock cycles.
2. When the device is configured as Transmission Enabled by DATA Pin Falling Edge, in order to issue
the TWI_RST command correctly, the first falling edge of the CLK should be sent t_CD after the DATA
falling edge, which should be longer than the minimum DATA setup time 20 ns, and shorter than 15 us,
