Switching between type 1 and 2 via SPI access. 2) The logic value of the COM receiver output (RX) is available if the SPI communication is disabled (SPI_EN_L = 1). 3) Driver strength is “double” – “WAKE_UP_MODE”. The total driver strength can be decreased by switching to type 4 (single strength). 4) Driver strength is “single”. The total driver strength can be increased by switching to type 3 (double strength) |
