4. Reduce EMI Function
The SM59364 allows user to reduce the EMI emission by setting 1 to the bit 0 (ALEI) of SCONF register. This function
will inhibit the clock signal in Fosc/6Hz output to the ALE pin.

Note1:Under steady state (non-transient) conditions, IOL must be externally
Limited as follows : Maximum IOL per port pin : 10mA
Maximum IOL per 8-bit port : port 0 :26mA
port 2,3
:15mA
Maximum total IOL for all output pins : 71mA
If IOL exceeds the condition, VOL may exceed the related specification. Pins are not guaranteed to sink current
greater than the listed test conditions.
