When the UiRRM bit (i=0 to 2) is set to "1" (continuous receive mode), the TI bit in the UiC1 register is
set to “0” (data present in the UiTB register) by reading the UiRB register. In this case, i.e., UiRRM bit
is set to "1", do not write dummy data to the UiTB register in a program. The U0RRM and U1RRM bits
are the bit 2 and bit 3 in the UCON register, respectively, and the U2RRM bit is the bit 5 in the U2C1
register.
When the U2LCH bit in the U2C1 register is set to "1" (reverse), the data written to the U2TB register
has its logic reversed before being transmitted. Similarly, the received data has its logic reversed
when read from the U2RB register. Figure 14.13 shows serial data logic.
The CLKMD1 to CLKMD0 bits in the UCON register can choose one from two transfer clock output
pins. (See Figure 14.14)This function is valid when the internal clock is selected for UART1.
