NAME
AD[6]/
TITD
TYPE
I/O
FUNCTION
Data Bus D[6] or Address/Data Bus AD[6]/Transmit Internal Termination
Disable
A[6]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[6].
AD[6]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the
multiplexed address/data bus AD[6].
AD[5]/
RMODE1
TITD: In Hardware Mode (BIS[1:0] = 11), it disables the internal transmit
termination.
Data Bus D[5] or Address/Data Bus AD[5]/Receive Framing Mode Select
Bit 1
A[5]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[5].
I/O _{AD[5]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the}
multiplexed address/data bus AD[5].
AD[4]/
RMODE0
RMODE1: In Hardware Mode (BIS[1:0] = 11), it selects the receive side
operating mode.
Data Bus D[4] or Address/Data Bus AD[4]/Receive Framing Mode Select
Bit 0
A[4]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[4].
I/O _{AD[4]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the}
multiplexed address/data bus AD[4].
AD[3]/
TSM
RMODE0: In Hardware Mode (BIS[1:0] = 11), it selects the receive side
operating mode.
Data Bus D[3] or Address/Data Bus AD[3]/TS_8K_4 Mode Select
A[3]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[3].
I/O AD[3]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the
multiplexed address/data bus AD[3].
TSM: In Hardware Mode (BIS[1:0] = 11), this pin selects the function of
TS_8K_4. See the register descriptions for more detailed information.
Data Bus D[2] or Address/Data Bus AD[2]/RS_8K Mode Select/Serial
Clock
A[2]: In nonmultiplexed bus operation (BIS[1:0] = 01), it serves as the data bus
D[2].
AD[2]/
RSM/SCLK
I/O
AD[2]: In multiplexed bus operation (BIS[1:0] = 00), it serves as the
multiplexed address/data bus AD[2].
RSM: In Hardware Mode (BIS[1:0] = 11), this pin selects the function of
RS_8K. See the register descriptions for more detailed information.
SCLK: In Serial Port Mode, this pin is the serial clock input.
