DIVIL Register Descriptions (Continued)

5.6.2.2

Local BAR - KEL from USB Host Controller 1 (DIVIL_LBAR_KEL1)

See Section 4.6.1 "LBARs and Comparators" on page 97 for operational details.

The KEL registers take 4 kB of memory space. However, only offsets 100h, 104h, 108h, and 10Ch contain registers. All

other writes are “don’t care” and reads return 0.

This is one of two KEL LBARs. Each LBAR “hits” to the same KEL. This allows USB Host Controllers at different addresses

to be used, if desired. Both LBARs do NOT have to be used.

5.6.2.3

Local BAR - KEL from USB Host Controller 2 (DIVIL_LBAR_KEL2)

See Section 4.6.1 "LBARs and Comparators" on page 97 for operational details.

The KEL registers take 4 kB of memory space. However, only offsets 100h, 104h, 108h, and 10Ch contain registers. All

to be used if desired. Both LBARs do NOT have to be used.
