12.4 Operation
If the real-time output operation is enabled by setting the RTPC0.RTPOE0 bit to 1, the data of the RTBH0 and RTBL0
registers is transferred to the real-time output latch in synchronization with the generation of the selected transfer trigger
(set by the RTPC0.EXTR0 and RTPC0.BYTE0 bits). Of the transferred data, only the data of the bits for which real-time
output is enabled by the RTPM0 register is output from the RTP00 to RTP05 bits. The bits for which real-time output is
disabled by the RTPM0 register output 0.
If the real-time output operation is disabled by clearing the RTPOE0 bit to 0, the RTP00 to RTP05 signals output 0
regardless of the setting of the RTPM0 register.
