1.6 Reset SER/Sensor configuration and enable DFE module

#Hard reset SER

reg_0x58 = board.ReadI2C(DesAddr,0x58)

reg_0x58 = reg_0x58 | 0x60 # Enable I2C Passthrough with auto ACK

board.WriteI2C(DesAddr,0x58,reg_0x58)

board.WriteI2C(serAlias[rx_port],0x01,0x02) # Ser Hard Reset

time.sleep(0.01)#wait 10ms

board.WriteI2C(serAlias[rx_port],0x0A,0x12)

reg_0x58 = reg_0x58 & 0x5F # Disable auto ACK and I2C passthrough

board.WriteI2C(DesAddr,0x58,reg_0x58)

board.WriteI2C(DesAddr, 0xB1,0x90)

board.WriteI2C(DesAddr, 0xB2,0x40)

board.WriteI2C(DesAddr, 0xB1,0x71)

board.WriteI2C(DesAddr, 0xB2,0x20)

time.sleep(0.0001)#Wait 100us
