37.3.17 RTP Pin Control 8 Register (RTPPC8)
This register configures the internal pullup or pulldown on the input pin. A secondary function exists when
the pull configuration is disabled and a pulldown is selected. This will disable the input buffer. Figure 37-25
and Table 37-26 describe this register.
NOTE: If the pullup/down is disabled in the RTPPC7 register and configured as pulldown in
RTPPC8, then the input buffer is disabled.
