RESET
I6246RESET: Active Low input that initializes or re-initializes the
DP83846A. Asserting this pin low for at least 160 µs will
force a reset process to occur which will result in all internal
registers re-initializing to their default states as specified for
each bit in the Register Block section and all strapping op-
tions are re-initialized.
