12.3 Registers

RTO is controlled using the following two registers.

• Real-time output port mode register 0 (RTPM0)

• Real-time output port control register 0 (RTPC0)

(1) Real-time output port mode register 0 (RTPM0)

The RTPM0 register selects the 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.

RTPM0m

Real-time output disabled

Real-time output enabled

Control of real-time output port (m = 0 to 5)

RTPM0 0 RTPM05 RTPM04 RTPM03 RTPM02 RTPM01 RTPM00

After reset: 00H R/W Address: RTPM0 FFFFF6E4H

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. In order to use this register as the real-time output pins (RTP00 to RTP05), set

these pins as real-time output port pins using the PMC and PFC registers.
