Output AB8
Line Add Bus Data (LADATA[7:0]). The add bus data
contains the SONET transmit payload data in byte
serial format. All transport overhead bytes are set to
00h. The phase relation of the SPE (VC) to the
transport frame is determined by the Add Bus
composite timing signal LAC1J1V1 and is SW
selectable to be either 0 or 522. LADATA[7] is the most
significant bit (corresponding to bit 1 of each serial
word, the first bit to be transmitted).

LADATA[7:0] is only asserted during the SONET/SDH
tributaries assigned to this device as determined by the
LAOE bit in the TTMP Tributary Control registers.
LADATA[7:0] is updated on the rising edge of
LREFCLK.
LADP
Output W10
Tristate
Line Add Bus Data Parity (LADP). The Add Bus data
parity signal carries the parity of the outgoing signals.
The parity calculation encompasses the LADATA[7:0]
bus and optionally the LAC1J1V1 and LAPL signals.
LAC1J1V1 and LAPL can be included in the parity
calculation by setting the INCLAC1J1V1 and INCLAPL
register bits in the Master SONET/SDH Egress
Configuration register high, respectively. Odd parity is
selected by setting the LAOP register bit in the same
register high and even parity is selected by setting the
LAOP bit low.
LADP is only asserted during the SONET/SDH
tributaries assigned to this device as determined by the
LAOE bit in the TTMP Tributary Control registers.
LADP is updated on the rising edge of LREFCLK.
LAPL
Output Y11
Tristate
Line Add Bus Payload Active (LAPL). The Add Bus
payload active signal identifies the payload bytes on
LADATA[7:0]. LAPL is set high during path overhead
and payload bytes and low during transport overhead
bytes.
LAPL is only asserted during the SONET/SDH
tributaries assigned to this device as determined by the
LAOE bit in the TTMP Tributary Control registers.
LAPL is updated on the rising edge of LREFCLK.
