XR16V598
2.25V TO 3.6V HIGH PERFORMANCE OCTAL UART WITH 16-BYTE FIFO
Each bit selects sampling rate for that UART channel, for example, bit-0 is channel 0. This register associates
with 4XMODE register to decide the sampling rate (16X or 8X or 4X). When 4XMODE [7:0] = 0x00, Logic 0
(default) selects normal 16X sampling with logic one selects 8X sampling rate. Transmit and receive data rates
will double by selecting 8X.
