37.3.10 RTP Pin Control 1 Register (RTPPC1)
Once the pin is configured in functional mode (using RTPPC0 register), configuring the corresponding bit
in RTPPC1 to 0 will not disable the output driver. Figure 37-18 and Table 37-19 describe this register.

Bit Field Value Description
31-19 Reserved 0 Reads return 0. Writes have no effect.
18 ENADIR Direction of RTPENA pin. This bit defines whether the pin is used as input or output in GIO mode.
This bit has no effect when the pin is configured in functional mode.
Read:
0 Pin is used as input.
1 Pin is used as output.
Write:
0 Configure pin to input mode.
1 Configure pin to output mode.
17 CLKDIR Direction of RTPCLK pin. This bit defines whether the pin is used as input or output in GIO mode.
This bit has no effect when the pin is configured in functional mode.
Read:
0 Pin is used as input.
1 Pin is used as output.
Write:
0 Configure pin to input mode.
1 Configure pin to output mode.
16 SYNCDIR Direction of RTPSYNC pin. This bit defines whether the pin is used as input or output in GIO mode.
This bit has no effect when the pin is configured in functional mode.
Read:
0 Pin is used as input.
1 Pin is used as output.
Write:
0 Configure pin to input mode.
1 Configure pin to output mode.
15-0 DATADIR[n] Direction of RTPDATA[15:0] pins. These bits define whether the pins are used as input or output in
GIO mode. These bits have no effect when the pins are configured in functional mode. Each bit [n]
represents a single pin.
Read:
0 Pin is used as input.
1 Pin is used as output.
Write:
0 Configure pin to input mode.
1 Configure pin to output mode.
