PRODUCT SPECIFICATION
To derive the required RCAP2H and RCAP2L values from a known baud rate, use the
equation:
RCAP2H,RCAP2L = 65536 –

When either RCLK or TCLK is set, the TF2 flag will not be set on a Timer 2
rollover, and the t2ex reload trigger is disabled.
10.9.2.2 Mode 1 Transmit
Figure 10-12 illustrates the mode 1 transmit timing. In mode 1, the UART begins
transmitting after the first rollover of the divide-by-16 counter after the software
writes to the SBUF register. The UART transmits data on the txd pin in the following
order: start bit, eight data bits (LSB first), stop bit. The TI bit is set two clock cycles
after the stop bit is transmitted.
