FUNCTION
Ground
Active-Low Reset Output. RESET remains low while VCC is below the reset
threshold and for at least 100ms after VCC rises above the reset threshold.
RESET is open-drain on the MAX6328/MAX6348 and push-pull on the
MAX6326/MAX6346.
Active-High Reset Output. RESET remains high while VCC is below the reset
threshold and for at least 100ms after VCC rises above the reset threshold.
