CHI Transmit Time-Slot Enable Registers (FRM_PR49—FRM_PR52)
These four registers define which transmit CHI time slots are enabled. A 1 enables the TCHIDATA or TCHIDATAB
time slot. A 0 forces the CHI transmit highway time slot to be 3-stated. The default value of this register is 00 (hex).
Table 173. CHI Transmit Time-Slot Enable Registers (FRM_PR49—FRM_PR52) ((691—694); (C91—C94))
CHI Receive Time-Slot Enable Registers (FRM_PR53—FRM_PR56)
These four registers define which receive CHI time slots are enabled. A 1 enables the RCHIDATA or RCHIDATAB
time slots. A 0 disables the time slot and transmits the programmable idle code of register FRM_PR22 to the line
in the corresponding time slot. The default value of this register is FF (hex).
Table 174. CHI Receive Time-Slot Enable Registers (FRM_PR53—FRM_PR56) ((695—698); (C95—C98))
CHI Transmit Highway Select Registers (FRM_PR57—FRM_PR60)
These four registers define which transmit CHI highway TCHIDATA or TCHIDATAB contains valid data for the
active time slot. A 0 enables TCHIDATA, and a 1 enables TCHIDATAB. The default value of this register is
00 (hex).
