Concentration Highway Interface
CHI Timing with CHIDTS Enabled
Figure 38 illustrates the CHI frame timing when CHIDTS is enabled (registers FRM_PR65 bit 1 (TCHIDTS) and
FRM_PR66 bit 1 (RCHIDTS) = 1) and ASM is disabled (register FRM_PR44 bit 2 (ASM) = 0). In the CHIDTS
mode, valid CHI payload time slots are alternated with high-impedance intervals of one time-slot duration. This
mode is valid only for 4.096 Mbits/s and 8.192 Mbits/s CHI rates.
