21. Serial Interface (UARTi (i = 0 or 1))
21.3.3 Continuous Receive Mode
Continuous receive mode is selected by setting the UiRRM bit in the UiC1 register (i = 0 or 1) to 1 (continuous
receive mode enabled). In this mode, reading the UiRB register sets the TI bit in the UiC1 register to 0 (data
present in the UiTB register). If the UiRRM bit is set to 1, do not write dummy data to the UiTB register by a
program.
