13.3 Registers
CHAPTER 13 REAL-TIME OUTPUT FUNCTION (RTO)
RTO is controlled using the following two registers.
• Real-time output port mode register 0 (RTPM0)
• Real-time output port control register 0 (RTPC0)
Caution In order to use the real-time output pins (RTP00 to RTP05), set these pins as real-time
output port pins using the PMC and PFC registers.
(1) Real-time output port mode register 0 (RTPM0)
The RTPM0 register enables the selection of real-time output port mode or port mode in 1-bit units.
This register can be read or written in 8-bit or 1-bit units.
Reset sets this register to 00H.
After reset: 00H R/W Address: FFFFF6E4H

0
Real-time output disabled
1
Real-time output enabled
Cautions 1. By enabling the real-time output operation (RTPC0.RTPOE0 bit = 1), the bits
enabled to real-time output among the RTP00 to RTP05 signals perform
real-time output, and the bits set to port mode output 0.
2. If real-time output is disabled (RTPOE0 bit = 0), the real-time output pins
(RTP00 to RTP05) all output 0, regardless of the RTPM0 register setting.
3. When writing to bits 6 and 7 of the RTPM0 register, always set 0.
