Signal Name:
Signal Description:
Signal Type:
Clock used to clock data through the receive-side framer. This pin is normally connected to RCLKO. Can be
internally connected to RCLKO by connecting the LIUC pin high.
4.3 Parallel Control Port Pins
Signal Name:
Signal Description:
Signal Type:
Flags host controller during conditions and events defined in the status registers. Active-low, open-drain output.
Signal Name:
Signal Description:
Signal Type:
A dual function pin. A 0-to-1 transition issues a hardware reset to the DS2155 register set. A reset clears all
configuration registers. Configuration register contents are set to 0. Leaving TSTRST high tri-states all output and
I/O pins (including the parallel control port). Set low for normal operation. Useful in board-level testing.
Signal Name:
Signal Description:
Signal Type:
Set low to select nonmultiplexed bus operation. Set high to select multiplexed bus operation.
Signal Name:
Signal Description:
Signal Type:
In nonmultiplexed bus operation (MUX = 0), these serve as the data bus. In multiplexed bus operation (MUX = 1),
these pins serve as an 8-bit multiplexed address/data bus.
Signal Name:
Signal Description:
Signal Type:
In nonmultiplexed bus operation (MUX = 0), these serve as the address bus. In multiplexed bus operation
(MUX = 1), these pins are not used and should be connected low.
Signal Name:
Signal Description:
Signal Type:
Strap high to select Motorola bus timing; strap low to select Intel bus timing. This pin controls the function of the
RD (DS), ALE (AS), and WR (R/W) pins.
If BTS = 1, then these pins assume the function listed in parentheses ().
Signal Name:
Signal Description:
Signal Type:
In Intel mode, RD determines when data is read from the device. In Motorola mode, DS is used to write to the
device. See Bus Timing Diagrams.
