CHAPTER 13 REAL-TIME OUTPUT FUNCTION (RTO)
User’s Manual U13850EJ6V0UD
473
13.7 Cautions
(1) Before performing initialization, disable the real-time output operation by clearing bit 7 (RTPOE) of the real-time
output port control register (RTPC) to 0.
(2) Once the real-time output operation is disabled (RTPOE = 0), be sure to set the same initial value as the output
latch to the real-time output buffer registers (RTBH and RTBL) before enabling the real-time output operation
(RTPOE = 0
→
1).
(3) Operation cannot be guaranteed if a conflict between the following signals occurs. Use software to avoid a
conflict.
•
Conflict between the switch operation from the RTP mode to the port mode (RTPOE = 1) and the valid edge of
the selected real-time output port trigger
•
Conflict between the write operation to the real-time output buffer register (RTBL, RTBH) in the RTP mode and
the valid edge of the selected real-time output port trigger
