(1) Disable real-time output.
(2) Perform initialization as follows.
(3) Enable real-time output.
(4) Set the next output value to the RTBH0 and RTBL0 registers by the time the selected transfer trigger is
(5) Set the next real-time output value to the RTBH0 and RTBL0 registers via interrupt servicing corresponding to
(1) Prevent the following conflicts by using software, such as by writing to the RTBL0, RTBH0, and RTPC0
(2) Before performing initialization, disable real-time output (RTPOE0 bit = 0).
(3) Once real-time output has been disabled (RTPOE0 bit = 0), be sure to initialize the RTBH0 and RTBL0
