If SCSN remains LOW for longer than 16 clock cycles, it recognized as an SPI error.
When this happens, the SPI error flag is set and pin SDO goes to a high-impedance state
until the next falling edge on pin SCSN.
An SPI error is also assumed if fewer than 16 clock cycles are received while SCSN is
LOW. If this happens, the SPI error flag is set.
All status bits are refreshed once the status register has been successfully read.
When the transceiver is in simple error indication mode the SDO output is in a
high-impedance state and pin SCSN is in pull-down mode. In SPI mode pin SCSN is in
pull-up mode.
SPI readout is not possible when the transceiver has detected an undervoltage on V
