• Bit 2:0
These bits specify the number of IDLE bits of guard time that are inserted in between PDI recep-
tion and transmission direction changes. The default guard time is 128 IDLE bits, and the
available settings are shown in
tion, the guard time should be set to the lowest safe configuration accepted. No guard time is
inserted when switching from TX to RX mode.
