4.25.1PrimeCell Modifications

The PrimeCell UART varies from the industry-standard 16C550 UART device as follows:

•receive FIFO trigger levels are 1/8, 1/4, 1/2, 3/4, and 7/8

•the internal register map address space, and the bit function of each register differ

•the deltas of the modem status signals are not available.

•1.5 stop bits not available (1 or 2 stop bits only are supported)

•no independent receive clock.
