Output bit, that provides information to user as to which port is active, if SEL_

OUT = ‘LOW’, then Port A is active, if SEL_OUT = ‘HIGH’, then Port B is

active. Only used when MS pin is ‘HIGH’

control is inactive and pin programmability is active. Pins 49-52 are control

pins only for Port A, S4-S7 and pin 19 is S2 and pin 20 is S3. If 'MS' =

"LOW", Port B cannot be configured and is left as default.
