(2) Real-time output port control register 0 (RTPC0)
The RTPC0 register is a register that 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 Tables
12-3 and 12-4.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.

Notes 1. When the real-time output operation is disabled (RTPOE0 bit = 0), all the bits of the
real-time output signals (RTP00 to RTP05) output “0”.
2. The INTTP0CC0 signal is output for one clock of the count clock selected by TMP0.
Caution Set the RTPEG0, BYTE0, and EXTR0 bits only when RTPOE0 bit = 0.
