1.62V TO 3.63V HIGH PERFORMANCE OCTAL UART WITH 16-BYTE FIFO
2.7
Transmitter
The transmitter section comprises of an 8-bit Transmit Shift Register (TSR) and 16 bytes of FIFO which
includes a byte-wide Transmit Holding Register (THR). TSR shifts out every data bit with the 16X or 8X or 4X (if
8X or 4X sampling is selected via the 8XMODE Register or 4XMODE Register) internal clock. A bit time is 16
(or 8 or 4) clock periods. The transmitter sends the start-bit followed by the number of data bits, inserts the
proper parity-bit if enabled, and adds the stop-bit(s). The status of the FIFO and TSR are reported in the Line
Status Register (LSR bit-5 and bit-6).
