Payload Time Slot Bus Transmit Stuff Indication: When high, indicates a stuff byte must be
transmitted in place of the data byte arriving 8 time slots later.
Payload Time Slot Bus Receive Data: This is the received serial payload data. It may be sampled
on the rising edge of TSB_CLK or on the falling edge, according to the RDAT_EDGE bit in the
RSIU Port Configuration Register.
Payload Time Slot Bus Receive Stuff Indication: When high, indicates that data on TSB_RDAT is
not valid data. TSB_RDAT is stuffed with all 1s.
Overhead Time Slot Bus Clock: This clock is based on SIB_TXHSCLK
the Overhead Time Slot Bus.
Clock Rate is 12.96 / 11.184 / 8.592 MHz.
Overhead Time Slot Bus Strobe: A strobe signal that indicates the start of a frame with 84 time
slots carrying Overhead data. The Strobe indicates the beginning of each Overhead time slot
Frame.
Overhead Time Slot Bus Transmit Data: This is the serial overhead data sent from the CX28500
to the other device. This signal may be driven on the rising edge of TSB_OCLK or on the falling
edge, according to the TDAT_EDGE bit in the TSIU Port Configuration Register.
Overhead Time Slot Bus Transmit Stuff Indication: When high, indicates a stuff byte must be
transmitted in place of the data byte arriving 8 time slots later.
Overhead Time Slot Bus Receive Data: This is the received serial overhead data. It may be

Overhead Time Slot Bus Receive Stuff Indication: When high, indicates that data on TSB_RDAT
is not valid data. TSB_RDAT is stuffed with all 1s.
