37.3.9 RTP Pin Control 0 Register (RTPPC0)
This register configures the RTP pins as functional or GIO pins. Once the pin is configured in functional
mode, it overrides the settings in the RTPPC1 register. Writing to the RTPPC3, RTPPC4, and RTPPC5
registers will have no effect for pins configured as functional pins. Figure 37-17 and Table 37-18 describe
this register.
