28.1.3 Reset
All GPIO registers are initialized on system reset. The data and data direction registers for all
ports (except as noted below) are cleared, configuring them as inputs. Port E[1:0] bits are
used for the LED outputs RDLED and GRLED respectively and are set to drive high. Port
G[3:2] bits are used for SLA[1:0] outputs and are set to drive low. Port G[1:0] bits are used
for EEDAT and EECLK respectively and are set up as inputs. All interrupt control and
debounce registers are cleared.
