XR17V354
HIGH PERFORMANCE QUAD PCI-EXPRESS UART
The Device Configuration Registers provide easy programming of general operating parameters to the V354
and for monitoring the status of various functions. These registers control or report on all 4 channel UARTs
functions that include interrupt control and status, 16-bit general purpose timer control and status, multipurpose
inputs/outputs control and status, sleep mode control, soft-reset control, and device identification and revision,
and others. Tables
registers is described in detail in the following paragraphs.
