(2) Real-time output port control register (RTPC)
Note RTP0 to RTP7 output 0 if the real-time output operation is disabled (RTPOE = 0).
This register sets the operation mode and output trigger of the real-time output port.
The relationship between the operation mode and output trigger of the real-time output port is as shown in Table 13-
3.
RTPC is set by a 1-bit or 8-bit memory manipulation instruction.
RESET input sets RTPC to 00H.
After reset: 00H
