15.1.3 Continuous Receive Mode
Continuous receive mode is held by setting the U0RRM bit in the U0C1 register to 1 (enables continuous
receive mode). In this mode, reading U0RB register sets the TI bit in the U0C1 register to 0 (data in the U0TB
register). When the U0RRM bit is set to 1, do not write dummy data to the U0TB register in a program.
