(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 the
(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
Clear the RTPC0.RTPOE0 bit to 0.
• Set the alternate-function pins of 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
Set the RTPOE0 bit = 1.

Notes 1. If the RTBH0 and RTBL0 registers are written when the RTPOE0 bit = 0, that value is transferred to
• Conflict between real-time output disable/enable switching (RTPOE0 bit) and selected real-time output trigger.
• Conflict between writing to the RTBH0 and RTBL0 registers in the real-time output enabled status and the
before enabling real-time output again (RTPOE0 bit = 0 → 1).
Set the PFC5.PFC5m bit and PFCE5.PFCE5m bit to 1, and then set the PMC5.PMC5m bit to 1 (m = 0 to 5).
Set the RTPM0 register.
Set the RTPC0.EXTR0, RTPC0.BYTE0, and RTPC0.RTPEG0 bits.
