2) Slew Rate Limitation
10M: Not use Slew Rate Limit ability. Maximum communication speed
921.6Kbps in this mode.
250K: Use Slew Rate Limit ability. Communication speed is limited
under 250Kbps.
Slew Rate Limit allows communication without errors by activating slew-rate driver to reduce
reflection waves and EMI electromagnetic waves. However, communication speed is limited
when it is used.
