• Bit 2:0 - GUARDTIME[2:0]: Guard Time
These bits specify the number of additional IDLE bits of Guard Time that are inserted in between
PDI reception and - transmission direction change. The default Guard Time is 128 IDLE bits,
and the available settings is shown in
nication, the Guard Time should be set to the lowest safe configuration accepted. It should be
noted that no Guard Time is inserted when switching from TX - to RX mode.
