Specifications

TLSB Bus 2-3
The TLSB implements parity checking on all address and command fields
on the address bus, ECC protection on the data field, and protocol se-
quence checking on the control signals across both buses.
2.1.5 TLSB Signal List
Table 2-1 lists the signals on the TLSB. Signal name, function, and de-
fault state are given. After initialization, the bus drives the default value
when idle.
