System Drop Bus Data (SDDATA[7:0]). The

System drop data bus is a time division

multiplexed bus which carries the E1 and T1

tributary data is byte serial format over the SBI

bus structure. This device only drives the data

bus during the timeslots assigned to this device.

SDDATA[7:0] is updated on the rising edge of

SREFCLK.

SDDATA[0] and SDDATA[4:7] share the same

pins as MVID[4] and MVID[5:8]. SDDATA[0] and

SDDATA[4:7] are selected when the

SYSOPT[1:0] bits are set to “10” or “11”, in the

Global Configuration register.

SDDP

Output

Tristate

System Drop Bus Data Parity (SDDP). The

system drop bus signal carries the even or odd

parity for the drop bus signals SDDATA[7:0],

SDPL and SDV5. Whenever the TE-32 drives the

data bus, the parity is valid.

SDDP is updated on the rising edge of

SREFCLK.
