Figure 29-10. CTS Lost
NOTE
If GFMR[CTSS] = 1, all CTS transitions must occur while the transmit
clock is low.
Reception delays are determined by CD as Figure 29-11 shows. If GFMR[CDS] = 0, CD is sampled on the
rising receive clock edge before data is received. If GFMR[CDS] = 1, CD transitions immediately cause
data to be gated into the receiver.
1. GFMR[CTSS] = 0. CTSP=0 or no CTS lost can occur.
