Revision 1.2
6.0 Host-Controlled Modules and Host Interface
Standard Logical Device Configuration Register Definitions
Write accesses to unimplemented registers (i.e., accessing the Data register while the Index register points to a non-existing
register) are ignored; reads return 00
(indicating that no DMA channel is active). The configuration registers are accessible immediately after Host Domain reset.
In the registers below, any undefined bit is reserved. Unless otherwise noted, the following definitions also hold true:
• All registers are read/write.
• All reserved bits return 0 on reads except where noted. To prevent unpredictable results, do not modify these bits.
• Write-only registers should not use read-modify-write during updates.
Use read-modify-write to prevent the values of reserved bits from being changed during write.
