On the DO line, data is generated from the µWire interface on SLCK falling

edge and read by the EEPROM interface on SCLK rising edge.

On the DI line, data is generated from the EEPROM interface on SCLK falling

edge and read by the µWire interface on SCLK falling edge.

On the DO line, data is generated from the µWire interface on SLCK falling

edge and read by the EEPROM interface on SCLK rising edge.

On the DI line, data is generated from the EEPROM interface on SCLK rising

edge and read by the µWire interface on SCLK rising edge.

Set up the interface by writing the following values in setup 1 register (SR1):

CS_EDGE_RD = 1

CS_EDGE_WR = 0

CSCS_LVL = 1

In this example, only two cycles (read and write) are described.
