Enhanced Local Bus Controller
10.1.3.2
The eLBC provides the ID of a transaction source on external device pins. When those pins are selected,
the 5-bit internal ID of the current transaction source appears on LSRCID[0:4] whenever valid address or
data is available on the eLBC external pins. The reserved value of 0x1F, which indicates invalid address
or data, appears on the source ID pins at all other times. The combination of a valid source ID (any value
except 0x1F) and the value of external address latch enable (LALE) and data valid (LDVAL) facilitate
capturing useful debug data as follows:
The LSRCID[0:4] and LDVAL signals are multiplexed with other functions sharing the same external
pins. Refer to
learn how to enable the LSRCID/LDVAL pins.
10.2
Table 10-1
also shows the reset state of all external signals during assertion of HRESET. For more information on the
use of some of these signals as reset configuration signals on the device, see “Power on Reset Flow.”

If a valid source ID is detected on LSRCID[0:4] and LALE is asserted, a valid full 26-bit address
may be latched from LAD[0:15] and combined with LA[16:25].
If a valid source ID is detected on LSRCID[0:4] and LDVAL is asserted, valid data may be latched
from LAD.
