REV. 1.0.0
HIGH PERFORMANCE 2.25V TO 3.6V QUAD UART WITH FRACTIONAL BAUD RATE
3.1.7.1 DVID [7:0] (default 0x48)
Device identification for the type of UART. The Device ID for the V794 is 0x44.
Examples:
XR16V794 = 0x44
XR16L784 = 0x24
3.1.7.2 DREV [7:0] (default (0x01)
Revision number of the XR16V794. A 0x01 represents "revision-A" with 0x02 for rev-B and so forth.
3.1.8 REGB [7:0] (default 0x00)
REGB[0]: Simultaneous write to all 4 UARTs
• Logic 0 = Write to each UART configuration register individually (default).
• Logic 1 = Enable simultaneous write to all 4 UART configuration registers. This can be very useful during
