(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) Sequentially set the next real-time output value to the RTBH0 and RTBL0 registers via interrupt servicing
(1) Prevent the following conflicts by software.
(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 registers

before enabling real-time output again (RTPOE0 bit = 0 → 1).
Clear the RTPC0.RTPOE0 bit to 0.
• Set the alternate-function pins of port 2 or port 5
• Specify the real-time output port mode or port mode in 1-bit units.
• Channel configuration: Select the trigger and valid edge.
• Set the initial values to the RTBH0 and RTBL0 registers
